Sunstream in Auburn makes the nicest but they are EXTREMELY overpriced.
Marine Floats is trying to unload a never used Hydrohoist. They won't tell you that they have it because of permitting gone bad though. It is Fire sale priced and brand new.

The Tacoma News Tribune had a big hero worship article on him about a year ago.
