Cisco offers its factory-refurbished Linksys E4200 Dual-Band 802.11n Wireless Gigabit Ethernet Router for $79.99 with free shipping. That's tied with our mention of a refurb from ten days ago and the lowest total price we've seen. (It's also $35 below the lowest total price we could find for a new one.) This 450 Mbps router supports simultaneous 2.4GHz and 5GHz frequencies and features four Gigabit Ethernet ports, a USB port, integrated UPnP media server, 3x3 MIMO antenna array, and more. A 90-day Cisco warranty applies.
