OK - I did a little more research and learned a few things.
1. The OS matters. So far Windows 7-64bit is generally reported to support touchscreen the best. HOWEVER the IS a "touch pack" service pac or driver thing for XP that is reported to be very functional.
2. Technology matters. There are 4 major touch-screen technologies and infra-red or "optical" appears to give the best touch-accuracy and clearest image quality. After reading enough reviews, I would say "optical" is the best way for us to go at this time.
The consensus seems to be that you need an "optical" monitor, Win7, and any other appropriate drivers to get good accuracy and responsiveness.
ACER makes a 23-inch high-def multi-touch that is only $329.00. It seems well reviewed.
At that price I would like to just go buy one and test SONAR out on it, but finances SUCK this month!
