Sturdy HP touchscreens (2) compatible with win 7 (maybe 8 too, haven't tried). I have used these as part of a dual screen setup for my convertible tablet pc's. Easy to connect and will include a USB dock to make it easy to connect multiple screens. Dual monitor stand is seperate ($150). Might be willing to discount if you buy the setup in bulk. Used during my time at Stanford and made everything more productive.
