Cisco Linksys Store via eBay offers the factory-refurbished Cisco Linksys 802.11n Wireless-N300 4-Port Router, model no. E900, for $19.99 with free shipping. That's tied with our mention of a refurb from last week and $19 under the lowest total price we could find for a new one. It features four 10/100 Mbps Ethernet ports, a data transfer rate of 300 Mbps, WPA2 and WEP security, and more. A 90-day Linksys warranty applies.
