I was learning the bassoon a few years back (I was renting one), however at the time purchasing one, whilst just about affordable, would have taken up more of my savings than I would have liked. I put it on hold and started the cello instead which was more affordable.
I'm thinking about taking it up again now I've changed careers (though possibly just contrabassoon this time because I preferred it after trying one), however I'd want to buy after renting for a couple of months. I've also got a career dilemma which could result in me spending quite a lot of money on training in a couple of years time, depending on how things work out. So, I'm in a position where I might want to sell an instrument I'd purchased to fund that. At the same time, it would seem daft to miss out on a potential hobby because of something that might happen depending on aptitude/the jobs market and other factors.
If I were to purchase a secondhand instrument (perhaps 20-plus years old but of a good quality), what would the depreciation be like over a couple of years? Do the instrument shops charge a lot of commission for a sale? Also, if I were to take an interest in joining an amateur ensemble/group, would they take someone who could play the contrabassoon (and strings) but who didn't have recent bassoon experience?
