Just upgraded my router so selling my previous one and also found an older one in the pile of stuff. Pick up around Newark.
Cisco/Linksys WRT160N - For the non-geeks in the room this is an 'N' router, it's really fast and gets good range. Has served me well, not sure when I bought it but probably 2 years old. Still a very sweet router.

Next up, I have a Linksys WRT54Gv2, this is the Honda Accord of wireless routers. It's several (5?) years old and is just a 'G' router so its a bit slower and doesn't have the range but probably still faster than your home internet. This was the most popular router sold for a long time. It's currently running custom firmware called DD-WRT (http://www.dd-wrt.com) which lets you do all kinds of fun things most routers don't normally do (like, hypothetically, boosting signal strength past FCC limits). If you don't care about any of that it doesn't really matter, it will still do all the regular stuff.
