Have seen worse though..

Actually the dish does not need to be Turkish - any dish will do as they all work the same way. What you need is a tuner to decode satellite signal and it also doesn't have to be Turkish. You'll just be able to watch all free satellite channels. The drawback is that probably there's not too big a choice of them - the only free Turkish channel I get from Hot Bird is Wedding Tv and it isn't really a Turkish channel anyway, it just has a Turkish dubbing. Anyway, it's not watchable at all! I have no idea if other satellites offer a better choice of Turkish free channels, you'd have to browse the list of what's on Astra etc.
The solution might be to buy a normal UK dish and a Turkish decoder with pre-paid licence/service fee. I am living in Ireland but I bought a Polish decoder and pre-paid two years of Polish TV. My brother organised it in Poland and sent it to me. Then it was just a matter of buying a normal satellite dish and positioning it.

Every satellite has a footprint meaning coverage area where its transponders are sending transmission.

For Turksat 2A the footprint as as follows:

and as for Turksat 1B and 1C

As you can see, in Ireland for example, you will be able to watch tons of Turkish language TV channels if you align your dish to that satellite. The closer to the center, the smaller the dish and vice versa. If you are in the hot spot a 60cms dish would be enough whereas if you are close to the limits of the transmission area a larger antenna will be required.

When I got mine installed I was told that I had to get two seperate dishes for hotbird and turksat. Originally I just wanted some cables drawn because I could get hotbird from the neighbour but there were no turkish channels so I had to buy a dish for turksat as well, which only has turkish channels. This was in Turkey though.
I think some uydu installers are taking advantage of costumers' lack of knowledge on this topic

Because there is a 90 degree angle between Turksat and Hotbird if you are facing Turksat direction your right arm would be Hotbird, very close to it is Astra which has a few HD channels as well as Spanish ones, a little to the right of it is Eutelsat W3 that transmits Digiturk channels. If you are into football you have live broadcast every weekend from Turkish League on LigTV and Premiere league on FoxsportHD both channels broadcast in high definition. With digiturk you also get National Geographic in HD as well as a few other similar channels.

Yes if only one could afford digiturk...

Well, I agree it is a rip off.
