Electronica Direct via Amazon offers the refurbished Linksys by Cisco 802.11n Wireless 4-Port Gigabit Ethernet Router, model no. E2000, for $31.99 with free shipping. That's tied with our February mention of a refurb and $28 under the lowest total price we could find for a new unit. (For further comparison, we did see a refurbished model for $2 less in December.) It features both 2.4GHz and 5GHz bands, WPA/WPA2 Personal and SPI firewall protection, and more.

It's unclear whether a warranty is included.
