Is there really a difference between these two recvrs? It seems like all I read is how bad each one of these recvrs are. I want to go HD but it looks like all I read about these two recvrs are negative. I'm a current D*tv subscriber. Checked w/ value electonics can get recvr for 315 and addt'l 50 for install. Called D*tv and got offered recvr and install for $270 but could not tell me what recvr. Value electonics is the RCA. Confused?? Any advice would be appreciated.
