Dave and Chuck Kessler are two people who really take the time to listen to your concerns. We talked about nickel plating(my two scatches turn out to be raised scatches-ie two small spots not buffed) and minor flaws in manufacture ,that every sax is bound to have, in great length. My nickel SX-90 was set up great by chuck no leaks. Very Very knowledgeable people about saxes. They helped me feel good about my purchase(I was on the fence)by bein genuinely honest a bout the sax and not at all being pushy. Great bunch of people at Kessler!!!!!
