No Problems here. It depends how it is installed. Yes, The 129 has a lower signal strength than the 119/110 but that should not have anything to do with picture breaking up if it is pointed correct. I have a 129 dish 1000.2 and never loose signal or pixelating. If you want HD go ahead and get it, The installer will install a new dish and you can watch the signal meter on your TV while he is pointing it. Ask him/her to put the 129 signal meter on the check switch screen while he/she is pointing the dish. It's all in the installer my friend. 129 satellite in Phoenix, AZ is usually at around 55% with the signal modifications. I use a birdog meter so I tweek the signal max while I am pointing. I would say "Go For It"
