I went into my local Target (Waterford Lakes location in Orlando, FL) and saw tons of stuff in many departments put on clearance. Most notable to me were the MN-740 Xbox Wireless bridges for $40 (normally $80 or $100 depending on the store). I know you can configure them on the Xbox then use them for other ethernet devices, but I'm not certain if you could also configure them with a regular PC as well, though I really don't see why not.
