Greetings from Naranjito... Signal quality is good, I have a 5' antenna for satellite 110 and a 4' antenna for the 119. My receiver is a 510 and has proven extremely reliable.
When it rains very hard, I lose all signal but then that happens probably once every two months...
Have had no need for customer service, but from what I've read it's a matter of luck reaching a good CS representative.
Can't comment on HD because I have SD...
My installer was Skytenna. I am very pleased with them and recommend them highly.
BTW, you have to make sure there are no tall buildings or trees west of your location... Dish Network satellites are very low on the horizon at this latitude, that's why we need the bigger dishes.
I used to have BUD too... A Uniden 4000 and a Motorola Sidecar...
