I have had comcast and now using bellsouth fast access. Only reason why I switched is b/c comcast customer service sucks. They are both pretty good. No problems with bellsouth yet. Only problem I had with comcast was every few months the internet would reset it self and it made me go through settign up comcast on my pc all over again and people at comcast had no clue why. They just gave me a shortcut through the comcast setup.
