These are made in MI - http://www.harbor-master.com/grand-r...elite-lift.htm
Not terribly well known. But they have a good price point. They have extremely low force required to lift the boat (it rolls up the bar on wheels instead of pivoting or lifting)
One cable, lowers down very far (good for inboards)
Fairly inexpensive. Perhaps not as heavily constructed as Shore Station - but far easier to live with.
