I'm sure some of you have seen the mod of a 360 controller put in a PS3 controller. I doubt many have the time or capability to that mod.
While surfing around I came across the Cross Battle Adapter.
This adapter allows you to plug in wired 360 controllers to your PS3 and use them with full rumble support. Only downside is Siaxis doesn't work.
I love the 360 controller and was so happy to finally see a simple solution to get one to work on a PS3. Not to mention you can make any button rapid fire.
I had to order one. If interested you can find them here for $49 bucks.
