Buying on ebay can be quite risky therefor with a major purchase it is wise to use an escrow service. I bought the Ditson mandolin referenced by Willie O. It is a beautiful instrument well worth about 2x what was paid. By the way Willie O it is a Martin C model not a B model that does sell for 500 -600 dollars. We have bought others too a Lachenal Concertina, that is a wonderful concertina. However do your homework, check references & feedback. Buyer beware!!!!
