Yes, I can't wait for more Street Fighter action!

http://www.xcm.cc/XFPS_360_PRO.htm It's quite steep in price (I paid like $80 for it) but it works really well; haven't had any response-delays or anything like that when I play games. See, I have weird hands so I was always better with a PS2 (or SNES) controller than I ever was with an arcade stick; I'm terrible with arcade sticks, actually. Haha.
