Book of Exalted DeedsApostle of Peace: Gets an ur-priest styled fast casting progression without progressing your own spells. Good in some places, but not for a pure cleric.
Celestial Mystic: 7th level, 3 feats. D4, drop BAB, drop fort, gain 4+ skills, 9/10ths casting. Some okay effects, but nothing worth the feats or costs.
Fist of Raziel: 8th level (earlier if get BAB from somewhere), 2 feats (1 is good). Get d10, full bab, drop will, 9/10ths casting, paladin style abilities. 10th level ability is quite good. If you want to do the melee cleric, this plus ordained champion is pretty golden.
Lion of Talisid: 6th level, need to wrangle in animal companion and summon natures ally 2. Gain 4+int skills, and a bunch of druid/ranger abilities, including wildshape. Depending on how hard it is for you to get an animal companion and summon natures ally 2, this can be quite good.
Prophet of Erathaol: 7th level, 4 bad feats. D6, drop BAB, gain ref, 9/10ths casting. 1 crummy class ability.
Sentinel of Bharri: 5th level, 2 bad feats. D4, drop BAB, drop Fort. 4+int skills. Polymorph into a bear, and get a class ability called "Cavalry of Dire Bears" which is pretty awesome in name, but not ability. The trade offs are more or less fair; you do gain some quickened spells, which is decent.
Skylord 10th level, 3 feats, lots of not-class skills. Get d10, full BAB, will turns to Ref, but still 5/10ths casting.
Swanmay: 5th level, 2 feats, need wild-empathy from somewhere. Full BAB, drop will, 4+int skills, 9/10ths casting. Gain fey type at 10th level, but otherwise, worse than Fist of Raziel for similar benefits and costs.
Wonderworker: 5th level, 2 feats; d6, 4+ skills, drop Fort, drop BAB. Gives you bonus spells. If you're level 17 and fill out last 3 levels with this; you trade 1 seventh level spell slot for two 8th level spell slots. If you've got practised caster, it's okay; the class returns the feats it wastes, sorta. So, mostly even trade offs.

Book of Vile DarknessDiabolist: 5th level, d4, 2 feats, drop fort, drop bab. Do a bit of extra spell damage. No thanks.
Disciple of Asmodeus: 6th level, 3 feats. D6, drop fort, gain 4+ skills. Get a bunch of command style abilities, but nothing worth 6/10ths casting. The first level doesn't cost a caster level and gets you...a bonus to gather information. In terms of dips, there is far better. In terms of taking more levels, there is still far better.
Thrall of Demogorgon or
about equal if you take a 4 level dip: 6th level, 2 feats. Drop will save, gain full BAB, 4+int. 4/10ths casting; but you get caster levels at 1 and 4. All 10 levels is awful, but taking 4 levels gets you the 4th level ability; +2 natural armor, and 2/day getting two full round actions in a single round. Basically like having two belts of battle, if your DM doesn't allow MIC and does allow BoVD. 4 levels is pretty good if you're not getting extra actions from elsewhere : (see this guide:
http://brilliantgameologists.com/boards/index.php?topic=7515.msg247178#msg247178)
Thrall of Gra'zzt: 5th level, 2 feats. D6, 4+skills. 6/10th casting, gain damage on spells. Not good.

Dragonslayer: 2 bad feats (one can be bought, one can be domained or class featured in). Level 7. Gets martial weapons, tower shields, d10, full BAB. 5/10ths casting lost at even levels; good 1 level dip if you already have feats. 1 level dip =
greenDragon Lyrist: 1 feat, 2/5ths casting, clearly meant for bard but can qualify and progress cleric. D6, ref rather than fort, 4+int skills. Get meh abilities.
Platinum Knight: 7th level, 1 feat. 5/10ths casting, loss at odd. Full BAB, paladin style abilities, but nothing worth caster loss.
Talon of Tiamat: 6th level, 1 feat, 5/10ths casting, loss at odd. Breath weapon style abilities, but nothing worth massive caster loss.

Drow of the Underdark:
Arachnomancer: Need a 2nd level arcane spell, but can progress cleric. Bad feat, gets you lowered hit dice, ref instead of will/fort, and 5/8ths casting. Nah. 1 level gets you a ref save bump, no caster level loss, and the spider domain, but there are better dips.
Demonbinder: Need invocations, 5th level. Text says progresses invocations; chart says any class. 9/10ths casting. Gain lots of small abilities and resistances. Might be used for filling out an Eldritch Disciple build. Still bad there.
Eye of Lolth: Cleric/Rogue prestige class; 5th level for skills, can be entered Rogue 2/Cleric 3. ½ casting, d6, 4+ skills makes this blatently worse than Church Inquisitor, Shadowbane Stalker, Seeker of the Misty Isle, etc.

Mage killer: 3 bad feats, maybe 4. 7th level. D4, drop bab, drop fort. Gain spell focus things
Master Alchemist: 3 feats, 7th level. D4, drop BAB, drop fort. Brew massive potions (4 up to 9th level spells per day), but potions are still non-optimal.

Shining SouthHalruaan Magehound: Drop BAB, Drop Fort, D4, 3 bad feats. 8/10ths casting, loss at 4 and 8. Gain resistences, magic sensing, and an anti-magic field you really don't want. Even 3 levels is terrible; if you want a dip, you're way better off with Divine Orcale, Contemplative, Church Inquisitor, etcetera.
Hand of the Adama: 5th level. No tough requirements, drop fort save. Gaing some healing/piercing illusion abilities. This one is passable.
Scourge Maiden: 6th level, 2 bad feats. Full BAB, 3/6ths casting; but losses at even levels. First level gets you a BAB and weapon focus, but still not worth the feats invested. Going further is a hideous mistake.

Arachnomancer: Progresses any but requires arcane spells; 7/10ths casting; so better than the reprinted one.

Heirophant: Reprinted in core, still terrible.
Shadow Adept: 5th level, 2 feats. Drop fort, bab, d4. Level 1 gets you 3 bonus feats, which is pretty funny. Gain shadow style abilities that are all decent, but you're losing a fair bit of the core cleric chasis. Reprinted elsewhere.

Corrupt Avenger: This prestige class is not meant for clerics.
Death Delver: This prestige class is not meant for clerics.
Tainted Scholar: This prestige class is not meant for clerics.
Libris MortisMaster of Radiance: 5th level, no feats. 4+ skills. 4/5ths casting. You're still losing a caster level for crummy abilities.
Master of Shrouds: 2 feats, as early as 3rd level. Drop fort saves, 9/10ths casting; but you get really badass summons.
Sacred Purifier: 5th level; requires extra turning get some RsoP styled abilities, but 4/5ths casting, and basically, the abilities are weaker.
True Necromancer: 5th level; cleric 3/wizard 1 will do it. Lose caster levels at 1 and 2, and 6 and 7 (they progress arcane/divine but not both at those levels). At the same time you get weak spell like abilities. If you need filler at the end of a mystic theurge build (Wiz 1/Cle3/MT10) and your DM doesn't let you just continue MT, I guess you can use this; but you'd be better off with a strong Wizard Prestige class like Incantatrix, or a strong cleric one (Contemplative, Divine orcale, etc).
Master Vampire: Have to be vampire, 2/3rds casting, d12, 4+int skills, drop BAB. Get more spawn, turn resistence, etc, but you have to be a vampire; which has bad LA.

Planar Handbook:
Doomguard: 10th level, 2 bad feats. 5/10ths casting, full BAB. D12, drop Will. All martial weapons, and terrible, terrible abilities; including only getting ½ healing.
The Mind's Eye: 5th level; RP requirements and skills; d6, 4+ skills, get ref not fort/will. 5/10ths casting; though the first level doesn't lose casting and is sorta okay, but still there are a wide array of better dips.
The Ardent Dilettante: Requirements tiered based on levels in prestige class (seriously?): Drop BAB, drop fort/will for ref; 6+ skills, all skills are class skills. 1st level requirements are easy, 4th are slightly harder (martial weapons) 7th are stupid (both arcane and divine casting), 10th are harder (Exotic weapon and a bunch of skills). 9/10ths casting. Gain skill bonuses, lore, spell like abilities, 3 bonus feats, ability to repeat cast others spells, and no level loss on death. It's a pretty okay prestige class, except terribly strange.
Defiant: This prestige class is not meant for clerics.

Scion of Tem-Et-Nu: 7th level, Get d10, full BAB, but 5/10ths casting. You gain a bunch of abilities, some are good, some are weak (Fast healing 5 in Rivers),
Walker of the Waste: Arguable as early as level 3 if you take Sand and Thirst domains; intended is level 5. 8/10ths casting, Drop BAB, drop fort, d6, turns you into a Dry Lich. Arguably passable.

Tome of Battle:
Ruby Knight Windicator: 5th level. 8/10ths casting (though you're likely to drop a level and end up with 17 CL to get into this); drop fort, full BAB, 4+ skills. Gets some weak manouver progression from Devoted Spirit, Shadow Hand, Stone Dragon, and White Raven, which is a decent enough set. 7th level ability is totally awesome, trade turn undead shots for swift actions. It's really a question of whether you're doing something else with your turning attempts or not (like DMM persist).

Tome of Magic:
Tenebrous Apostate: 5th level; not sure what the multiclassing looks like (I don't know Tome of Magic very well, I'm afraid). No feats. 4/5ths casting. Turning damage, Tenebrous progress, ac and skill bonuses, do more damage to undead, etc. Really can't comment on this one.
Child of Night 5th level, 9/10ths casting. No feat requirements. Get blur, cold resistence. D6, drop BAB, drop Fort. I continue to admit my inability to judge this prestige class.
Master of Shadow: 5th level. 9/10ths casting, Drop BAB. Resist cold, empowering your familiar, etc.
Brimstone Speaker: 7th level, 6/10ths casting, skills only. Fire damage ability and summoning ability.
Fiendbinder: 7th level, skills only. 7/10th's casting. D6, drop BAB, drop Fort. Bind a fiend as companion; summon fiends, can gain yourself some abilities.
Anima Mage: "Anima mage from Tome of Magic has an adaption for clerics... it's really good, 3/day free metamagic (and as a cleric, you prolly have persist anyway), some vestiges give turn attempts (tenebrous and the green lady vestige from pathfinder), which can be used to fuel divine or devotion feats, full casting progression, full soulbinding progression, lose bab and fort. Could be blue imho." (Thanks Waazaraath)
Qualify level 4 or 5, 1 feat. D4, drop fort, drop BAB; full casting; gain free metamagic 1/day at 5/7/9, capstone gives you 1/day still, silent, immediate spell; extra spells instead of vestige abilities, and vestige progression. Pretty good.

Manual of the PlanesDivine Agent: 6th level, no feat, okay requirements. 4 skills, drop fort. 5/10ths casting; bonus domain at 1 (casting loss at odds). Level 9 gets you DR 20/+1 (20/magic, I think), and 10 gets you gate; so that's almost okay except for the massive casting loss.

Skilled Cleric:
Elven: Rogue 1/Cloistered Cleric 3/Church Inquisitor5/Shadowbane Stalker 3/Seeker of the Misty Isle 4/ X4 (you can progress shadowbane stalker or Seeker of the Misty isle and lose a second caster level, or cleric or Church Inquisitor).
Get: (8+int*4) + 3*6 + 5*4 + 3*6 + 4*6 plus whatever you get your last 4 levels...so ~6+int skills/level.
You could also mix in spellwarp sniper (4 skills)
Or: Elven Cloistered Cleric 3/Church Inquisitor 5/Master of Masks 2/Shadowbane Stalker 3/Seeker of the Misty Isle 4/ X3
Melee cleric:
Simple: Cleric 5/Ordained Champion 5/Fist of Raziel 10: 18BAB, 17 casting.
Complex: Cleric 3/Church Inquisitor 1/Ordained Champion 3/Fist of Raziel 10/X3 17-19 BAB (depending on .5, .75, or 1), casting 18 as long as the last 3 levels have full casting.
Tome of Battle Melee Clerics:
Cleric 4/ToB class 1/RKV 10/X5 (you've got 13 or 14 BAB, so if X5 is 0.5, you get 15-16, 0.75, you get 17-18, and full BAB = 18-19, though you might have to lose caster levels to do that; and you don't want to lose more caster levels).
Decent ideas for X5: Contemplative 1 or 2, Divine Orcale 2: Evasion in Plate, RsoP 2 or 5: greater turning, empowered healing, etc. , Fist of Raziel 5 (If you can stand having 16 CL), Ordained Champion 5 (If you can stand having 15 CL), Church Inquisitor 1 or 2, Sacred Exorcis
Caster Cleric: You really want Dweomerkeeper if you can get it. Otherwise Contemplative, Divine Orcale, RsoP are all good enough.
