One of you tech's out there, please help.. Right now I have a dish 1000 with a DPP twin for the 110/119 satellite that has given us problems since it was set up for our 622. We have a separate dish 500 for the 129. I was thinking of buying another Dish 500 but what LNB's is the most reliable, the Legacy twin, Dual legacy or the Legacy Quad, I need some input before I buy one. Any help would be appreciated. I've been told that the DPP Twin has many problems, I think I have a bad one on my 1000 right now.
