And I love it. But then, I am a TVholic and have it on in the background nearly all the time. I've had both DirecTV and DISH at different times. When you need to upgrade equipment, sometimes it is cheaper to switch services, though I think they are starting to get better about customer retention practices.
For the premium movie channels, I like the Starz package rather than HBO or Showtime. Not only do you get a group of recent movie channels, you get a whole group of genre channels that run older movies - Western, mystery, romance, etc. And Starz has the new Torchwood series - just started this weekend!
DirecTV has Free Speech, Current, and Link channels, all of which have some good progressive programming. I am not sure at which tier those are available, though. Other channels to watch for are TMC, ION, NASA, Science, and HDNet. I think they give you all the channels to start so they can suck you into upping your subscription level.
If you have broadband you might want to compare satellite to getting a box that will stream Netflix and internet programming, like Roku. There is a DU Netflix Streaming Videos & DVDs Group -
