I'm trying to find some place that sells modded controllers. I'm specifically looking for controllers where the face buttons have some sort of turbo setting (rapid fire for the triggers is ok, but not what I'm looking for). I'm really good at button mashing, but I have a bad elbow because I use my entire arm to do it. And I have a lot of games that use button mashing mechanics. I'd really like to stop worrying about stressing my muscles too hard by going 5 hits per second when I know it's possible to get much higher without the pain. Any ideas?
