Being a newbie to the area, I got Comcast just before Christmas. Internet only, 25Mbps for $29 a month for 1st 6 months (plus "set=up" fees of course...). I've never used Comcast before, but their reputation proceeded them (customer no-service). So far though, no problems (touch wood) . Working great, fast, I use it quite a lot - streaming Netflicks, pandora, Vimeo (which is very bandwidth heavy) etc.
Their website is a disaster if trying to arrange a new service. Just a mess. Call them. One tip, if you know for sure you had Comcast cable service previously, it's a breeze to set-up and if it doesn't go right because of a screw-up on their end (happened to me), they will send out a tech at no cost. Also buy your own modem. It's cheaper than renting theirs after 9 months or so.
