He probably just wants one of those that uses USB. Not color or anything(well, red and black, or some 2 colors) I about purchased one a while back... Pretty neat and pointless ;P
Sorry I can't be of much help, but I don't remember what the particualr one I was looking at was called. BUT, you can probably find a few if you search on google. I've even seen some just plain LCDs that you could wire up and mount yourself on some old 5" dummy, if you feel like doing your own modding
