It would probably help if we had more information. Do you live in a big city or rather isolated area, or in-between? Are you willing to travel far to get a good deal, and where might that be? Anything against a used instrument? Alto or tenor? Do you have a friend who plays sax who can check out the instrument? Have you talked to the band director? How many music stores are there in your town? Any problem with online or mail-order type purchases? Anyway, lots of used Selmer Bundy or Yamaha YAS-23 instruments built for students, and can get a good deal as well as resale value on these horns, since many students start the sax, don't stick with it, and the horn goes on the market. Thus: Who can check out a used, How much, Where to buy/ can buy, When, Why we know, and What depends on the other info. This one shouldn't be a tough problem!
