Buy.com offers the ZyXEL 802.11n Wireless 4-Port Router, model no. NBG416n, for $18.99 with free shipping. That's tied with our May mention and the lowest total price we could find by $9, although we saw it for $2 less last summer. It features a high-gain 5dBi detachable antenna, WEP and WPA/WPA2 support, and more.
