Howdy, I have come across someone willing to sell me their flute. It's a Blessing and according to them it's in need of a few parts (screws and springs). I have yet to see the flute but their willing to let me check it out. My questions are: 1) What are the difficulties of obtaining replacement screws and springs on a flute? What are the [average] prices these parts go for? 2) Does brand TYPE affect the difficulty of repairs? 3) Is it worth it getting it fixed?
