This may have already been answered and I missed it but I called the "genius trust" at Dish Network today to find out the difference between the $10 fee for a 922 and the $6 fee for a 722(K) with a Sling Adapter. I was told that you would have the extra $4 if you had the 922 or the 722 series with the Sling Adapter. Is this correct or some more bulls*it from Dish? It don't really matter to me since I have a 922 and a Sling Adapter on the way from Claude, I am just a tight ass and try to save every penny I can.
