I despise Comcast.... You have no idea. I have such ill feelings that I troll them more than once a year..... Pretty much any given opportunity. Don't get me started.
Frontier isn't cheap either. But they provide a much better experience in my opinion. Equal up and down. Less issues with internal networking, it's fiber which would imply you are ready when and if Google ever comes out here. Do you know what else you get, or don't get i guess i should say:
Annoying splash screen telling me about copyrights
Astounding customer service

All adds up to a bill that you end up resenting yourself for when you pay it.
