I'd rather be in an open field than under trees with limbs and leaves and bird droppings. So we opted for the Traveler roof mount dish. That way we could upgrade our 2-HD DVR's to get a Genie and clients for other 2.
Decided to keep one DVR for bedroom and try Client on the outside TV. But the DTV Tech couldn't figure out how to hook it up. So DH talked to one of his subs and he had a box from DirecTV that mirrors the LR Genie. So far, it's the best choice since we don't pay extra fee for 3rd TV.
