Newegg offers the refurbished Asus Dual-Band 802.11n WiFi Gigabit Ethernet 3-in-1 Access Point / Wireless Bridge / Range Extender, model no. EA-N66, for $49.99 with free shipping. That's $10 under the lowest total price we could find for a new one, although we saw a refurb for $20 less last November. It features an orthogonal 3x3 antenna design. Deal ends February 28.

A 90-day warranty applies, but it's unclear who backs it.
