Could someone help me out. I am an old Dish user since 1997, I have two very old receivers (3000 & 3700) hooked to a legecy dual LNB Dish 300. I aquired a used 311 receiver and a Dish 500 dish with a Dish Pro Twin LNB. Would I be better off price wise to just add the receiver to my account or would it be better to cancel the old account and activate the Dish Pro receiver by itself. Im going to use a DP dual LNB, Dish 300 and a DP34 switch to try to get 61.5 satelite. In thinking that Dish could see that the two old receivers weren't there anymore what would happen?
