Amazon.com: http://www.amazon.com/Advanced-Dual-Band-Wireless-N-Router-Refu
has Cisco Linksys E2000 Wireless N Dual Band (not simultaneous) 4-Port
Gigabit Router DD-WRT/Tomato Compatible (refurbished) for $34.99 with free
shipping with Prime.
I know this has been as low as $29 but that was several weeks ago, and not
available from amazon for under $45 for the past three weeks.
Also, this can still be had direct from digitalEtc for $32.99 but I prefer
using my Prime and getting 2-day shipping. FYI, I have four and just
ordered my 5th. All four have flashed with Tomato firmware and work like a
charm. Why so many you ask? I've kept 2 and the others I've been setting
up for family... Great unit at a superb price point.
