Okay, I'm starting to buy components again for my CNC machine.

Mach3 I have not bought yet, as well as the computer.

I have seen people using a touchscreen, an old Point of Sale units for the touchscreen.

I looked at Newegg and they have 5 different types of touchscreens for a 1920x1080p. Yes, I know, Mach doesn't need to be that good of resolution, but, hey! I want to play WoW or another game while I sit there and watch/wait for crap to cut out.

Anyway, what type of touch screen do I need with Mach to make it work? Will any touch screen work? Or is there something else I need to buy as well?

Is there a software I need to run in the background and program buttons to make it work with Mach 3?
