I plan to switch from DirecTV to Dish Network in the next month. I will be doing my own installation as I have a tile roof and don`t want to take the chance on damage. I will be removing my DirecTV dish and using the current mount to install the Dish Network dish. I have 2 choices of dish configuration. The Dish 500 or the eliptical Dish 1000, (NOT the Plus models). I am interested only in the 110 & 119 satellites and will be using the DishPro Twin LNB. My question is which of these dishes would be the easiest to align for my usage AND which would give me the best signal??
