So I know that the Xbox 360 controller communicates through a Radio Frequency and not through Bluetooth like the PS3/Wii controllers do. The problem is that I just downloaded Steam/Portal for Mac, and I want to play it using a controller. Being an Xbox Owner, and not PS3, I'd rather use the Xbox 360 controller on my Mac.

I know that Microsoft sells an official RF receiver and with a few hacked Mac drivers, I can use it on my Mac. I think it would be easier to use a bluetooth controller, however.

So does anybody know where I can find a Xbox 360 Bluetooth Controller? It doesn't need to be official from Microsoft, in reality it's just a Bluetooth Controller that's been manufactured to look like the 360's controllers. I found one result on Amazon, but I doubt that that's the only one made.

Thank you very much!
