Grifter, if you are looking for a kb/mouse setup for your 360, stay away from the XFPS. I own one now, it's terrible. Deadzones are completely awful. Moving the mouse to quickly causes it to flip out and spin wildly.

If you want real kb/mouse feel, check out XIM360.

It's a bit more expensive, but it is extremely configurable and can be made to actually feel like a real kb/mouse setup.
