Hi All! I currently have three TVs with the following receivers: HR44-500 HR23-700 C41-500 (Genie Mini) I would like to upgrade to 4K on one TV. Also, the HR23 is old and doesn't work well. I called DTV and asked for upgrade deals and was told $646!!! to get new receivers. I have been with DTV for 24 years and have not paid for receivers in over ten years. What should I be asking for and shouldn't I be able to get new boxes for free or with offsetting credits?
