Are you looking for a vertical or a cantilever style? I was in your shoes late last season when my old hoist took a crap on my. I searched and found that what @oldjeep suggested is a good idea. Find out what's locally available and go from there. I looked at shorestation, shoremaster, hewlit, floe, max, and lakeshore as most are readily available in my area. I ended up getting the max. http://maxdock.com/vert_5000.php The reason I did this was that it's made locally, the extrusions seemed thicker than those of the competitors, the assembly seemed easy (have not yet assembled it), and maintenance of the pullies seems very easy. All moving parts have grease fittings and the pullies can be removed without have to partially or completely disassemble the cradle. Then, there was the cost component. I was getting more for my dollar with this hoist than the others. I ended up getting a powered hoist because I have a 120V beach circuit at my house that only has one receptacle on it, so it made sense to do that over the solar option.
