I am very happy with my Winegard Pathway X 2 auto seek carryout dish.
It supports two sat receivers. If you want HD, there are no carryout auto seek for Directv.
DISH has two sets of sats; an eastern arc for the east coast and a western arc for the west. In most of the country you can use either.
The Pathway is the only carryout that can get both. They are in different parts of the sky so it can be a big advantage to be able to select which arc you can see due to trees, etc.
I have DISH at home and just added a box to the rv.
The Pathway is about $400 delivered.
My Kharma ran over my Dogma.
