Been a while since I last posted and I've been out of the DVR loop for a long while, need a refresher course. 
I have a Dish 501, 40-hour, DVR. I'd guess its ~7-years old, works well most of the time, occasional flakiness. I'd like to upgrade to a dual tuner DVR that I assume I'll purchase on eBay. Current Dish Network DVR offerings all seem to have a monthly fee attached.
I currently have a single cable running from my Dish 500 with two LNB's which "see" 110 and 119 satellites.
I need a RF remote solution, inasmuch as I have a small TV connected to the composite out. I'll only have one TV on at a time so the single DVR can feed both TV's.
What DVR should I purchase and what other cable/dish pieces do I need?
Thanks for any advice.
