I also want to add to the comments I already posted that in the year I had Direct TV, the signal only went out once and it was during the heaviest ice storm pennsylvania had had in 10 years. the entire state was shut down for 3 days.
My mom also has dish and I constantly complain about the quality of the service when I'm at her house. Her hard drive is small, the channel selection sucks, and the system just seems to be poor quality. Worse than any of the three providers I've ever had
