As much as I hate the hopper, I would stay away from the 922. Pure garbage. I had one at one point trying to upgrade from a 722 and ended up going back to the 722.
Oh, what nonsense, I have been using a 922 since last February and I am currently on my only 5th replacement. It works just fine until it doesn't... Plus, Dish is very good at getting you a replacement within two or three days!
