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 $24.99 with free shipping. That's $25 under our mention from three weeks ago and the best no-rebate price we've seen. (It's also $21 below the lowest total price we could find for a new one.) It features an orthogonal 3x3 antenna design.

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