Can anyone tell me if there is an advantage to buying a receiver frombest buy as an upgrade, or just getting one fromDTV, im tired of used crap, I swear to god I am..I joined in May, got an old beat up box, added another DVR in June for 199 more and got another used machine..I want another one, but I am afraid to order from DTV site...If I order it from best buy Will I get a newer model? also WIll I own it?
