I know I need a decent amount of resolution, but not sure exactly what I need until I build one and test it. I do know I need more than 8 bit. Figured I'd jump to 12 and try that first. Those chips don't seem too expensive. I've got the A to D conversion figured out code-wise, just need to do the same for D to A. 

I'm all about keeping it simple and Jon says the LTC1257 chip is easy to use, so I'll try that first.
