There's a handful (5 or so) of HD channels that come off satellite 110 (500 will pick up Sats 110/119 normally) that are in Dish America packages. If you want a Dish America Package, you'll need a 1000.4 (EA or WA) to receive the vast majority of your channels.
I can always get you information on upgrading the dish if you PM your phone number/account number.
Also, I don't know what receivers you have, but they will need to be HD receivers if you wish to have a DA package.
