You have already said that you would be looking to sell your 722 if you cancel service. I would be willing to do a straight swap: I'll send you my unused Hopper Duo, and you can send me your old 722.
Huh. I have an unused 722 (built-in OTA) as well. Will the Hopper Duo go on the Hybrid LNB alongside the H3? (I don't think so.)
