I recommend a Hori Pad turbo ps3 controller. Wireless and you can adjust how rapid you want it (5X a second, 10X, etc.) I bought my first one on ebay for like $35. I just bought another one I saw at Fry's Electronics for 39.99. Goes through a pistol clip in about 1.5 seconds on full speed. Ppl will hate you, but Last Stand is lethal! BTW a LOT of ppl use them already anyway, so I look at it as staying even
