My neighbor is wanting to enter the world of HD. He has Comcast but wants to sub to E* because of more HD channels. Long story straight he has a Dish 500 with a DPP LNB. He gets low to mid 70's on both sats. The 129 maybe difficult to bring in. So it wants to use a Dish 1000.4 as a wing dish with the tilt set to 0. Just run a line from the 1000.4 with a DP LNB to the satellite in on his Dish 500 with a DPP LNB.
