Hi Pauline, are you looking for channels which broadcast in English or for specifically English programs?
We have a system called NILESAT, which gives us hundreds of channels about 15 to 20 of which are in English most of the time, i.e. BBC World, CNN, Aljazeera, Press TV, MBC 2 & 4, MBC Action, Fox Movies, Fox Series, Dubai 1, Infinity, Panorama Action, and more. Adds up to about 4 news channels and the others are mainly films. Not all the film ones are English ALL the time but it gives you a pretty fair choice.
We DON'T get Corrie or Eastenders or anything like that, but you buy the sat dish and box for a one off payment and that's it. We've had ours for over 3 years and are quite happy with it. No idea how much it would be now, I think it was about 450TL when we had ours.
