Bein and Fushi is a well-known instrument appraiser/restorer/dealer– their selection of violins is incredible, and if you’re in the market for a truly find instrument I’d recommend it here. While they are based in Chicago, they fly out to potential buyers(I’m in CA). I almost bought a violin from them years ago, and they were fairly good about the process, although I did feel quite a bit of sales pressure. I suppose the fact that I was 14 at the time might have gotten the dealer to push me a little harder than he would an adult, but still, it’s not like you’re selling cars. Otherwise all the dealings I’ve had with them are professional and courteous.
