newegg again offers the refurbished D-Link DIR-655 Xtreme N 802.11n Wireless 4-Port Gigabit Router, model no. DIR-655, with a Service Net 1-Year Extended Replacement Warranty for $29.99 with free shipping. That's tied with our expired mention from five days ago as the lowest total price we've ever seen for the DIR-655. (It's also currently $25 less than the lowest total price we could find for a new unit.) Features include WEP, WPA, and WPA2 encryption.

Note that a 30-day parts and labor warranty also applies, although it's unclear who supplies it.
