They are fine fella, it just depends on the size of the dish. You will get Sky anywhere in the UK even with a 40cm dish, as the footprint on Astra 2D is gigantic (it even runs down to about middle Spain, and as far as Cyprus and Southern Spain with a 2m dish).
Its not like terrestrial, so long as you are within the footprint and the dish is big enough, you should be okay.
I think to get 100% coverage in the UK of Sky, you need a 60cm dish minimum.
As for any other services though, im afraid I dunno anymore, I lost interest a couple of years back. Dont forget, if you want Freesat FS, you can easily buy a cheap ass Sky box on eBay as well as the OEM box from Aldi.
