We have had Dish for 7 years and are fairly happy with it, but we want a DVR preferrably with dual tuner. Right now we only have one receiver and would like to add one on. I know about the 721 and would love one, but don't want to pay that much. I would probably even try a 522, but of course they aren't available to me. I can get a 2 room DirectTV with Tivo installed for $49. I called Dish and was offered a 510 for $99 plus two $5 monthly fees. I'm not impressed with that. DirectTV's package is more monthly and they said I would have to wait up to 45 days for my network channels after filing the paperwork. If I use my billing address which is a rural route and box # I'm not eligible for NBC, but if I use my street name I am. Do you think I can get by with that? We actually watch quite a bit on NBC and I don't want to lose it. I would appreciate any input! Thanks!
