My contract is up in June. Would like to get 2 HR-24's to replace my original HR20-700's. Realize that the only way to insure getting the HR-24 is to purchase them. Even purchasing them they still would not be owned but leased. Question is if one of the HR24's went bad would DTV replace it with another HR24 or would I be at risk of getting an older model and lose my HR24? Also, if you purchase the HR24's is it possible to get some relief from DTV when activating them? Have been a DTV customer for a long time.
