In all honesty, you would just need the EA dish after you "move" but you would want the other dish until the tech puts in the EA dish. You can get away with just one dish, EA, as long as you change your service address to one that is in a EA DMA. You listed three that you said were on EA, so if you get an address within there, then all your channels would come off 110/119/129 on the two EA sats. The only thing you would run into would be if you had SD equipment, then it doesn't work with EA satellites. Only MPEG4 equipment does which is VIP and above.
