Belkin offers its factory-refurbished Belkin N150 802.11n Wireless Router, model no. F9K1001, for $14.99. Coupon code "NEWYEAR20" cuts it to $11.99 and bags free shipping. (Project Contact via eBay charges the same.) That's the lowest total price we could find for a refurb by $8. (It's also $13 below the best price we could find for a new model.) It features data transfer rates up to 150Mbps. A 90-Day Belkin warranty applies when Belkin is the seller.

Update: It's now sold out at Belkin; however, Project Contact via eBay still offers it for $11.95 with free shipping.
