How much $? My guess is that a nice sax isn't cheap. Still, it would be really cool to have one in my studio and to try and learn the basics.
My guess is that this a good price for a nice sax. As a hobbiest, you are right it is too much money.
Really thinking of selling it, might trade it for a good acoustic guitar, mine old loved guitar is falling apart. I'll have to make the rounds at the music stores and see what I can get. I hate big buttery acoustics, actually preferring a thin shitty sound so maybe this isn't a good trading position.
I'm not much good at selling instruments, but I have friends that make decent livings at buying old gear/vinyl etc and selling it on ebay. Might try that route first, then use the cash to buy that thin, shitty sounding guitar.
