Altatac via Newegg offers the refurbished D-Link N900 Dual-Band 802.11n Wireless 4-Port Gigabit Router, model no. DIR-855L, for $29.95 with free shipping. That's tied with our November mention of a new unit, which required rebate hassles, as the lowest total price we've seen. (It's $10 under the best price we could find for a new unit today.) It features up to 450Mbps speeds on both 2.4GHz and 5GHz channels and four Gigabit Ethernet ports. Deal ends January 27.

A 90-day warranty applies, but it's unclear who backs it.
