I have a brand new, in box one of these, the IOGEAR GBU421:

It's a very compact USB Bluetooth adapter. Lets you hook up certain wireless keyboards, mice, and Bluetooth headsets to your computer. I'm selling since it turned out that I had an old Bluetooth adapter lying around that I'd forgotten about.

Pick up from Studio 6.
