I know several of you, but not all.

So I'm not some random internet dweeb asking for help.
I recently got an XBOX 360 (user name REALFozzyBear) and I was wondering if there was any real solutions for using a keyboard and mouse on the 360?
I have been trying to play COD4 & I am extremely frustrated by the "standard' controllers. ANY suggestions would be appreciated.
