For its "M" Club members only, mwave.com offers the factory-refurbished Linksys WRT54GS 802.11g 108Mbps 4-Port Cable/DSL Router with SpeedBooster
with free shipping
. (You can join the "M" Club for free via the link on the product page.) That ties our mention from two weeks ago and is $25 less than the lowest total price we could find for a new unit.
Note that a 90-day warranty is included, however, it's unclear who backs it.
