we have given up on satellite tv. it's too expensive. we are considering comcast(only local cable provider) cable tv and Internet bundle known as "double play" service. the bundle will require use of a cable modem. comcast will lease one at $7/month. we want to own one, not lease it. are any of you willing to share your experience with either comcast and/or modem usage? will you recommend brands of modems under $80?
