Newegg offers the refurbished Asus N750 Dual Band 802.11n Wireless Gigabit Router, model no. RT-N65R, for $39.99 with free shipping. That's tied with last week's mention as the lowest price we've seen without rebate hassles. (For further comparison, it's also $30 under the lowest total price we could find for a new one.) It features a maximum speed of 750Mbps, dual-band support, four Gigabit Ethernet ports, two USB 3.0 ports, and three internal antennae.

A 90-day warranty applies, although it's unclear who supports it.
