I would like to know who has a xbox controller for thier computer. And Is there any good key mappers other than xpadder?

I would like to know who has a xbox controller for thier computer.

I do have a wired 360 controller for my computer, but I use it for games that already have provisions and mapping for it.  Otherwise it's the most precise and high quality controller you can buy for the pc by far.

What are some good games?

For the pc, Crysis and Crysis Warhead will play just like an XBOX game.  It gives you an ingame popup that shows you all the buttons when you plug it in.  Most new games that have the Windows brand on the cover have the same feature.  One downside is it will act like any other game controller with older games, but you still get a ton more precision over the generic controllers.  That is definately a plus for casual FPS's.  Oh,one more game that recognizes the 360 controller is Super Meat Boy which is significantly more enjoyable to play with.

I know Just Cause 2 supports it. I actually want to get one so I can use it with Dolphin and Metroid Prime, it is hard to play that with just a keyboard.
