PacificGeeks has an open frame 19" touch screen monitor for $290 with free shipping. Mechanical specs are here. It has a serial EX-II touch screen controller from 3M, with drivers available for linux and many versions of windows from 3M.
You can buy it from Pacific Geeks directly, However, get an account at Jellyfish and go search for EFL-1902X (this link does that), and you will get an extra 1.5% back.
I've seen the free shipping come and go on this item. Shipping for one to Chicago was about $25, so it is nice to get the free shipping. If you sign up for PacificGeek's mailing list, you might well get a % off or $ off coupon you can apply.
