Unfortunately, it's not a dream to use: http://jseliger.com/2008/02/25/another-public-service-announ... . Maybe things have improved since then.

BTW, like the OP, I have expensive Comcast service because I have no other effective choice, and they just sent me a box and let me set it up too.

If you know you are going to use Comcast for a year or more, it is cheaper (or break-even) to buy your own modem. Amazon has the Motorola surfboards (SB6120 and SB6121) for $75 and $85, respectively (vs. $7/mo *12mo=$84).
