DigitalEtc via Amazon offers the refurbished Linksys by Cisco 802.11n Wireless 4-Port Gigabit Ethernet Router, model no. E2000, for $34.99. With free shipping, that's $35 under the lowest total price we could find for a new unit. However, we saw another refurb for $3 less last month (since expired). It features both 2.4GHz and 5GHz bands, WPA/WPA2 Personal and SPI firewall protection, and more.
