TigerDirect via eBay offers the refurbished Linksys by Cisco 802.11n Wireless 4-Port Router, model no. WRT120N, for $18.99 with free shipping. That's a buck under our November mention and $6 below the lowest total price we could find for a refurb today. (It's also $20 less than the best deal we could find for a new one.) This router features four Ethernet ports and both WPA2 and WEP security.
