I have had a suitcase type satellite kit and found it a pain to line the dish up on site. This is due to the small size of the dish needing to be more accurately set.
A long time ago I had a tripod mounted Sky dish and Sky box system. It was easy to align and I would definitely recommend that system over the suitcase type. You should have no problem finding a used dish and box for little money. Somewhere here I should still have the tripod.
