Newegg offers the refurbished Asus 802.11n Wireless 4-Port Gigabit Dual Band Router, model no. RT-N66, for $44.99 with free shipping. That's tied with our refurb mention from two weeks ago and $44 under the lowest total price we could find for a new unit. It features four Gigabit Ethernet ports, three antennas, and USB. Deal ends October 24.
A 90-day warranty applies, but it's unclear who backs it.
