Price of Satellite TV per month?

My roommates are moving out of my house, so bills will be tighter but I still want TV. So I want lower my costs per month. I currently have Cable (Time Warner) and classic 70 channel TV (not Digital) is $76 per month.

I am looking into switching to Satellite when they move out, but would like an answer from people who currently have it what the exact cost ends up being per month, and I have some questions.

1) How long does the promo price go?

2) I just have one HD TV where I'd like the box receiver to be. Will my other TVs have any channels on them if I don't purchase other boxes?

3) Is it easy to get out of the Premium channel offers once they run out before you get charged for them?

4) Is the first receiver box that you get (like Hopper for Dish) free?

5) Does this hopper act as a DVR, and is that service free?

6) Will my HD TV automatically have a lot of HD channels without paying anything more?

Let's say I want the smallest package of channels (which would pretty much match up to what I have now with classic cable but have a few more channels and music channels), and I want one box (assuming the other TVs in my house will still get something without boxes), and no premium packages (like Movie channels, Blockbuster, or sports subscriptions) what will bare-bone price be per month, so I can see if it will be worth switching.
