Ocean Reef Electronics via Amazon offers the refurbished 5th-generation Apple AirPort Extreme 802.11n Wireless Gigabit Base Station, model no. MD031LL/A, for $66 plus $6 for shipping. (Click "these sellers" then "Refurbished from $66..." to find it.) That's $18 under our March mention of a refurb and the best price we've ever seen. (It's a current price low by $3.) This 802.11n wireless 3-port Gigabit router has a USB port for sharing a printer or hard drive and works on both 802.11g and 802.11n frequencies simultaneously.

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