2 SKY options? Really. Both SUCK! One grown daughter had Dish and the other Direct TV. Neither could keep a decent signal. Cost just as much as cable after the initial a sucker is born every minute contract runs out. Satellite - sucks. And you have to buy packages from them too - can't just pick and choose the channels you want (at least not the last time I checked - has that changed).
My signal rarely goes out. That is with either service. If you are worried about the cost after the intro contract ends, you can always switch between the two. I cancelled direct 7-8 months ago and they are still begging to take them back. Offering to pay the cancellation fee for Dish, free HBO and HD, equipment, sexual favors. You name it they want me back.
You can select individual channels but it is more expensive than just selecting packages. What do you want, free TV? You can still get that but will be limited to 6-7 channels.
