It's nothing special, but I have a Netgear W614 or something like that. It was $30 when we got it in like 2007 or 2008, and works fine still.
Price doesn't really relate to performance in routers. My sister originally had one of the expensive Belkin routers, but it kept losing the connection from our cable modem. My neighbors got the same model, and it couldn't stay up for more than about 10-15 minutes.
Just keep checking places like Amazon and Newegg for a decent router at a good price. You're right though that there isn't any reason to go to Best Buy and buy a basic one for $60-70.
