I see all of these vintage saxes on eBay. Band masters, stenciled Martins, King C Melody. All selling for cheap, between 100 and 300 US. They all say Pads and overhaul needed, but the key work moves freely. I was wondering if these horns would be a good way to learn some at home repair work without endangering my main sax. My main question is do those of you who might have more experience at vintage horns find that they often need extensive work that requires a professional or that they can be mostly taken care with basic repair kits so long as they are in good condition to begin with?
