Just make sure you can return it if unsatisfied. If not, don't make the deal.1) It sounds to me that I'm taking a chance getting a used horn since I guess I can't be sure of the condition?
I haven't played a Kessler stencil, but should your interest in soprano as a hobby wane, you won't get half your money back selling it. If you go for a decent used horn, you can generally get the value back that you initially paid should you need to move it.
