I have been with Dish continuously since 1999. Have two receivers: a 301 and a 2800. I have one HD set and am thinking about upgrading to HD. I have two dishes and get satellites at 61.5, 110 and 119. I subscribe to AT 200. I would want to swap out the 301 or the 2800 for a new HD receiver obviously. What increase in my monthly charges would I see? Would I be eligible for HD for life? Would my other non HD sets still be able to view what I watch on my HD receiver? I am on paperless and auto pay and live on Long Island.
