PS3 Eagle Eye Keyboard/Mouse adapterhttp://www.amazon.co.uk/gp/product/B0040UA...s00_i00_details
Only used it a couple of times. Can be a little annoying to setup but the fella does work.
You have to program the adapter on a PC for each button on the pad to used on the keyboard. I bought it for Battlefield 3 and it turned out I can't get comfortable in front of the 40'' TV with keyboard and mouse. Also to hold in a button on keyboard to zoom sniper rifle doesn't work well-- You can fix this by changing option to zoom on/off rather than hold to zoom. I don't like this method; so this is the reason for selling the adaptor.
