I see used Kay M-1's all the time, but how much would an old Kay C-1 go for? I've fallen in love with one and the thought of offering to buy it when I leave the school has crossed my mind more than once. It's a high school instrument, been around the block a few too many times, definately has had it's ass kicked, no structural problems to the body but the neck has been snapped and improperly repaired (the joint is coming undone causing the neck to bend forward) and it's just plain old and played a lot. How much do you think a fair offer would be if I was still in love by the end of next year?
