HD Programming

Last Christmas my husband and I bought a new HD widescreen tv. We have really enjoyed having the larger screen but now I would like to have some HD programming on it. We have DISH network and they do offer HD packages but we don't know if that is the route to go or if we should change to another provider. I hate to switch but then we do want the best deal. So, I guess we will just have to really compare and then decide.
