Hello, I'm new here. Can anyone tell me what the best DishNetwork Receiver is. I have one HDTV, and would like to go w/HD DVR Advantage. They're out of the vip612. Should I wait, or go w/ the 622? Is $100.00 too much for these receivers? Also, what satellite should I insist on? I have a 500 up there now, and the CSR said that may be good enough and depends on what the tech thinks when he gets here!!?? Is this right? Any advice is much appretiated.
