Yes that's right, the official Microsoft Xbox Wireless G Adapter for only $20 (plus ship). The catch is that there is no power supply included with this. Everything else is included though: box, manual, 6ft ethernet cable, setup disc, and of course the wireless G adapter unit. Tested and works great. I hear that this is also compatible with the 360 but I don't have one to test it out with.

This is a great deal if you can find a replacement power supply to use with it. Shouldn't be hard to find one though. Power specs are 6VDC, 1.0A with - O + polarity.
