The ViP722 series can feed two TVs independently- one HDTV and one SDTV. How many TVs and of what type will you use? Perhaps you could drop the 322 with a ViP722 series. But this path costs more each month than the 322 or ViP211, both in receiver fees and the DVR fee. EHDs from this receiver can be played by the Hopper.
The ViP211 series can be made into a DVR for a one time $40 charge and the purchase of an EHD. It feeds one TV, but you could hook up two, so long as both watch the same program at the same time. And this receiver, if owned, can be used with the Hopper system if you might go that route some day. But EHDs from this receiver cannot be played by the Hopper.
Sorry I don't have the exact dollars. Dish does not make this easy, finding a complete price list. It's there, just takes some hunting. Someone else will come along with that information, I'm sure.
