Why in the world would you go with Comcast? Assuming Google Fiber isn't available in your area, go with Cox or CenturyLink instead.
Comcast is currently the only option where I'm at, though another option is becoming available later this year(I'm not waiting even a month though). It isn't exactly my first choice, but at least it isn't too expensive.
