If I can add my two penn'orth her, I'm totally in agreement with Termie. I have two dishes installed at my house here in France. The French system was installed free by the local TV shop - free dish and installation plus a cashback of €100 against a monthly subscription. The English system I installed myself with the help of a friend - it's a Skybox I bought off Ebay, complete with free to air viewing card, for £15.00 including postage, along with a dish I bought cheaply at a local supermarket.
Friends of mine live about 5 miles from your parents' house and have a virtually identical system to mine.
The English guys who set up systems like this in France charge a fortune, because they can - they rely on the fact that there are plenty of timid English people around, who'd rather not deal with the French.
