Honestly I've got enough ground work laid I could throw up a sheet this weekend, just been so busy with the recent storms and such my creative juices are running low.

Warforged is a nice Rance Nashork. Wand-Sheath and the Arm-Crossbow are function arm cannons. They are a bit more expensive than they should be, however the WF Component section does state any magic item can come in Component form...
Wand-sheath won't help at all, no spellcasting or UMD, and none of the Warforged components really call to me for the Machine Mistress class. Warforged is a nice race, just not for this IMO.
However, I forgot the homebrew side of things. Neither of your links are exactly what I'm looking for Garryl, but they've given me some ideas about places to look. Thanks!
Edit: No luck with the homebrew, and I don't think I want another Warforged (I'm already playing two in currently running PbP games). Oh well, I don't need to be a construct so it isn't a big deal.
