Don't make them touch attacks. You already have the energy guns for that. Just reduce the prices. Start by working with the baseline (bows and crossbows) and build up from there.
Touch attacks make the energy weapons great as secondary weapons (since you can actually hit despite devoted next to no resources to it), but the high cost per shot makes them prohibitive as primary weapons. They can also be used well by proficient users willing to shell out the cash with grade 3 and/or HEX/Splash crystals, but again the price is too much to rely on. So make standard guns the viable primary weapon for the blaster master, who might switch to an energy gun for special occasions. Heck, better idea. Just cannibalize your existing energy guns. Make their standard shots be cheap (or even free) crystal bullets or whatever, with special energy crystals (like the Int'ars that they used for trained in SG-1) that can be fit in for an extra energy-based boost (namely, the current energy gun stats and effects). That way, you don't even have to re-enchant a second weapon when you want to pull out the big guns, and you get a similar effect to bows with enchanted arrows. The existing prices for the raw guns (without crystals) are already in the right range.
