Help selecting a system

My Satellite Setup
No set up yet, just getting started
My Location
Estonia (Tartu)
I have no system as yet, being in a difficult area for English language programmes--Estonia. Have received some good starting pointers from Rolfe and Spiney, but now its headache time:-bash.

Am trying to put together a system using a 120cm dish and whatever I can figure out from any replies received. Dish may have to be steerable, but is available here.

Can anyone suggest a reasonable system:)

Anything I cannot buy locally I can get from UK or elsewhere in the EU
