eXpansys offers the Belkin Share N300 802.11n Wireless Router, model no. F7D7302, for $19.99 plus $3.99 for shipping. That's the lowest total price we could find by $3, although we saw it for $6 less four weeks ago for Amazon Prime members. It features pre-configured security settings with WPA/WPA2 and WEP encryption, four 10/100 Ethernet ports, one WAN port, USB (for connecting a printer, hard drive, etc.), and more.
