Newegg offers the refurbished ASUS Black Diamond Dual-Band 802.11n Wireless N600 SOHO Router, model no. RT-N53, for $34.99. This $10 mail-in rebate cuts it to $24.99. With free shipping, that's $5 below our May mention of a new unit and $15 under the lowest total price we could find for a new unit today. This is a concurrent dual-band router, meaning it can run two separate full-speed 802.11n wireless networks at the same time. Rebate expires August 8.

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