I've always seen good recommendations for Franklin Frame, though have yet to send anything that way. I sent my Medici fork to Bob Freeman (Fausto Copious over on Classic Rendezvous), who passed it along to a plater he uses. It came back in fine shape. You can get an idea of before-and-after in my Flickr album. If you're not familiar with Bob's work, check out his Flickr albums. Basically, I'd trust him with anything related to vintage bikes.
