CowBoom offers the refurbished Apple AirPort Extreme 802.11n Dual Band Wireless-N Base Station, model no. MC340LL/A, for $89.99 with free shipping. That's tied with last week's mention, the lowest total price we've seen in a year, and $52 less than the best price we could find for a new one. Sales tax is added where applicable. This 802.11n wireless 3-port router has a USB port for sharing a printer or hard drive and works on both 802.11g and 802.11n frequencies simultaneously.
