Believe me if I had a choice I won't be using Comcast. The only other two possibilities for me are AT&T and Astound. But I found Astound doesn't service the area I moved into 6 months ago, which is about 3 miles away from where I used to live where they did provide service. AT&T does service my area but only at a paltry 3MB/sec option. So I'm stuck with Comcast for the foreseeable future.
I had a particularly bad experience with Comcast about two months ago and almost considered going to AT&T even at the much reduced speed.
