Three things are combining to make this Xbox 360 wireless receiver for Windows a fantastic buy. First, it's only $19.99. Second, Xbox 360 controllers like the Wireless racing wheel and even the standard ones are great. Most importantly, DirectX 10 and Vista's "Games for Windows" branding requirement is forcing every game developer to support all Xbox 360 controllers via Direct X. That means just about every game will have real 360 controller support.
As for the device itself, it connects via USB and can handle any combination of four controllers or headsets. Even new controllers like the Mad Catz arcade stick should be supported. Did we mention it's only $19.99?
