I put a 1000.4 at my brothers here in Central Maine and I ultimately switched to a DPP 500 and a DP 500 attached to the LNB IN today.
A couple of things about the DISH 1000.4 made it not worthwhile, namely the signal strength and the fact it's almost impossible to get a strong 77W with it. I say almost because I tried hard (but not too hard). I can get 50s-70s with the two dish solution (110/119, 61.5), I never saw above a 40 with the 1000.4. On average I saw 30's and high 20's.
My 2 dish setup rarely goes out except for huge downpour and usually only then does my 61.5 dish go out, the 110/119 seems to basically survive weather in general.
Basically I had a 100$ learning experience with the 1000.4.. I'm sure I can use it for something, maybe a motorized FTA dish later in time. It's rather heavy though.
