I'm switching from DSL to cable and am on the lookout for any cable modem deals. I know there have been lots of FAR deals in the past, but don't see any current ones.

Also I'm curious - are there modems/router combos or is a router something I'd have to buy later? I'm primarily interested in using the router for security - from what I understand (and please correct me if my understanding is wrong), one can use a router to keep the computer from being hacked?

Thanks in advance for the help.
