No. You will need one OR the other. If more than two receivers, then the DPP44, and a standard DP Twin.
As for E* shipping - folks are right. The "call back tomorrow" is scripted. I've never heard of anyone getting a tracking number.
I am SO glad we use a distributor instead of dealing with E* directly. When we place an order, our rep almost always
knows if it's ready to ship, and if he doesn't, he can walk 30 steps right into the warehouse to check.
I got my first Dish1000 less than 24 hours after they arrived at his place.
