A great place for refurbs is
Tiger direct , they have great prices and are well known to all who work custom and large volume. They own systemax machines and have a 25% stake in gateway. they have a section with only refurbs. i once bought a hardware based USRobotics modem for only 22.00 dollars there. (I live in miami by there headquarters and return center). they give NO WARRANTY whatsoever, but are dirt cheap. they carry linksys(crap) and some netgear and D-Link. If possible, find an MR814 router from netgear on pricewatch (again, never expect a warranty from these places) and use it. I've installed them on every IT service call i ever did when I worked for a network installlation company and i was so impressed i bought one myself.
It's both an wired and wireless router, offering better options and more flexability. Plus it just has great industrial design.
Also, turn WEP on! It's affect on speed is insignifigant and worth the extra security to stop an occasional network packet sniffer and IP range port scan. Also, change the default access code to the router after setup, to many idiots forget that can be the most crucial step to stoping snooping.
