...........That's the reason that Dish is moving towards Hopper/Joey system from the existing VIP 722 series specifically. In Hopper/Joey they can bill for each TV...where as in a 722, 2 TV functionality is built in. Another reason why 2nd 722 is billed $17 (not sure)
You sabotaged your own argument. A joey is $7, the exact same cost a VIP 722 is over a VIP receiver without a second output such as a 612 that costs $10.
