We have an 80cm aluminum dish from Dur-Line in anthracite. Unlike the cheap dishes of our neighbors, this one is not supposed to rust.. direct quote from our electrician
In addition, there was a 4-way LNB + cabling / sockets and chasing of the walls. It was mounted with a rafter bracket (I think it was called Herkules). I can't complain, despite a lot of wind in our area I've never had any problems with reception.
It all cost me about 600 euros (of which about 300 euros were for materials).
EDIT: Oh yes, I ordered the matching sealing stone myself (about 60 euros). Since we did the entire roofing ourselves.
