I bought one of these on a lark last week, and it's terrific...in just a week, my wrist and arm feel a million times better than they have in a long time.
It looks unwieldy in the pics, but it's really comfortable and not hard to get used to; it's light and works pretty well for general gaming, too (RTS, WoW, etc.). However, hardcore/twitch gamers would have to evaluate it for themselves. It comes with a driver CD (one of those mini CD-ROMs) and a USB-to-PS/2 adapter.
Granted, it's expensive, but if you suffer from wrist/hand fatigue, you might give it a try.
