Garhauer
I would recommend Garhauer ( http://garhauermarine.com/ ). I upgraded the mainsheet system on my 81' H30 to all Garhauer gear and have been very pleased with the performance, quality, and price of the parts I bought. I sent them some photos of my old setup and they helped me pick out the gear I needed to complete the project. Nice people, nice products.
