Newegg via eBay offers the refurbished Netgear 802.11n Wireless Range Extender, model no. WN3000RP-100NAR, for $32.49 with free shipping. That's the lowest total price we could find for a refurb by $3; a new one costs at least $37 more. (However, we saw a refurb for $6 less after rebate last month.) Features include WPA2-PSK, WPS, and WEP encryption and two external antennae.

A 30-day warranty applies, but it's unclear who backs it.
