So I have been with Dish for about 18 months now and I currently have a 722 and a 222k. I have a EHD with about 150 movies on it and I want to get rid of my 222k and get another 722 so I can move my EHD from the basement to the upstairs and be able to use it on either receiver. How much is Dish going to charge me for another 722? Thanks guys.
