Apple Store offers the factory-refurbished 5th-generation Apple AirPort Extreme 802.11n Wireless Gigabit Base Station, model no. MD031LL/A, for $85 with free shipping. That's tied with last month's mention of a refurb and $39 below the lowest total price we could find for a new one. 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 1-year Apple warranty is applied.
