Check out the HOT Deals forums here. They usually have deals on cable modems somewhere in there, just do a search for cable modem. Also make sure that the cable modem that you buy is compatible with the service that you get. The way it was with comcast for a while, a lot of modems wouldn't work with their service. I know the DLINK and LINKSYS didn't at the time. Not sure if they do now though.
