I'm going to subscribe to the Dish Network and I wanted to know my choices of receivers. I don't have HDTV and don't plan on one any time soon, so that won't matter. I want good sound, but my audio receiver is only 5.1 ready (my DVD has the decoder). I'm moving into a house that already had Dish Network and the dish is still on the roof. Is that any advantage? Any help is appreciated!
