In my humble opinion the best setup to begin with is:
Dish- at least 90cm, bigger is better ;-)
LNB- the fortec .4 db, invacom .3 db, there are a few reviewed in the reviews area
Motor-sg2100
Reciever- several to chose from, i would probably lean towards the pansat 3500 or the coolsat 4000 pro. The pansat 3500 has better support for AC-3 audio. There are LOTS of reciever reviews in the review area.
Hopefully this gives you some ideas..........
