Good to here from you. I teach middle school band at Jamesville-DeWitt and play/practice saxophone more then ever. Best bet to sell you horn is list it on SOTW. Search E-bay past sales for a price. There's a lot of good people on SOTW that can give you accurate info on your horn AND often saxophones come up for sale under-market value.
