hey guys, i'm looking to hack an original xbox  controller, so that i can use it to hook up a hacked SNES controller for playing console emulators.  i have found several tutorials on this online, and they look pretty straight forward( just alot of soldering).  i dont' want to hack up any of the controllers i have, so i will be looking for cheap ones at the flea markets and pawn shops.  are there any that are easier to solder to than others? i thought i remembered reading something about madcatz controllers being easy, but i wasnt sure if that was true, and if it is all madcatz controllers, or just specific ones?
any suggestions?
