Never heard of them. But there are somethings that you should check on all boats. Condition of the keel bolts, water in the hull core, water in the deck core, water leaking through deck fittings, water leaking through the deck-hull joint, water leaking through (insert name of boat here) The core can have some moisture in it and not be that big a deal or it could be rotted and the boat could be worthless. The boat won't look any different from the outside. Some people say "Oh I looked at it, it looked fine to me" Then they start trying to repair it and it is a disaster. It's good that you are asking questions now though before you commit.
From what I have seen most people on this board are more concerned with the condition of an old boat more than the maker. Of course the make is important but who cares if you have a freedom yacht if the hull and deck cores are rotted out inside?
