ive been playing games on my pc and the control pad im using (same as a ps2 control) is wearing out and not as responsive as it should be.wondered if its worth buying another controller or is it better to get the thing to use a ps2 controller on pc.if i get a controller i want to spend $20 max but i have a ps2 and 2 (ps2) controllers in my lounge room.any input on this would be appreciated.
