Touch screens
 

I tought they weren't affordable.

But when browsing through this mp3 jukebox article i stumbled upon Enablemart - products.

This firm sells add-on touchscreen kits for about 190 $ for a 15" kit.
Would be great to try that out. Almost all my database-forms use buttons and should work with this kit. Great and fairly cheap solution to give easy and speedy access to some co-workers.

a 17" CRT from Sony with touch screen capabilities cost around 2000EUR 2 years ago, prices are dropping :)
