Well i have a used model YAS-23 model yamaha alto saxophone. I have not touched the thing since high school (im 22) and i don't really see myself taking up playing again so i am trying to sell it. I got an ad on craigslist for 150, and a good amount of people are interested but i feel like im getting ripped off and its valued more. Is that a fair price to ask or not? It has some minor scratches but thats all.
