Best Touchscreen Monitor for Linux under $500

view story

http://unix.stackexchange.com – Looking for a 17" or larger touchscreen monitor that works with Linux. It will be used outdoor and I hear capacitive and optical screens are more durable. It doesn't need to be multi-touch. Please advise because I don't see Linux compatibility on the models I've seen, except for the expensive ELOS ones. Thanks (HowTos)
