Newegg offers the refurbished D-Link 802.11n Wireless Range Extender, model no. DAP-1320, for $7.99 with free shipping. That's $2 below our mention from last December of a refurb and the lowest total price we've seen in any condition. (It's also $27 less than the best price we could find for a new one elsewhere.) It delivers up to 300Mbps for whole-home coverage.

A 90-day warranty applies, although it is unclear who backs it.
