Yeah I just bought a system like this, still waiting on installation of the 2nd dish. The box got 'zapped' once already (after about 1 month), meaning you have to download new codes to break the scrambling but your satellite provider can do this on your pc in a few mins, you can even learn to do that yourself. This will happen once in a while. The only thing I dont like about this satellite system is that nobody can ever set the right time on the receiver, and the guides never seem to work right, so its hard to know what program is coming on next on which channel. I am sure there is a way to fix that, I just havnt figured it out and my satellite guy just doesnt understand how important that is.
I doubt that any satellite dishes were included in your quote, it sounds like just the price for the cardless receiver.
Originally they wanted to install two LNB's with one dish, however, I have heard that this does not make for good reception and thats much better to have two dishes instead.
