in the hardware section there is a thread about gamepads. For running all of the same class you need much fewer keys and macros to make things work because there isnt much to choose from. I have a G15 and an n52 and I currently only use maybe 20% of all the programmable keys on them to do stuff. Dont forget about the numpad.

Btw, you wouldnt happen to be the person I talked to on MSN last night? your setup seems familiar
