I have one HDTV and a standard definition one. Currently, I'm with Comcast here in the Boston, MA. who's got the best signal and drop off the least. because, I used to have DISH 2 years ago (Miami,FL) and the signal there was around 117!! I have read around here, people have very poor signal numbers. my last 3 bills(with Comcast) with them: $195, $167 and $178, thats with no movies bought or premium channels and with internet (which I'm willing to keep). thats way too much money! Please help! what are my options?
