Unpopular opinion time. First, I'm from a younger generation than many people on this forum. So I wasn't doing the vintage drum thing during the height of the market that everyone refers to here, and I can't speak from that experience.
But, I have zero sympathy for hoarders and collectors when the market goes down. Drums are utilitarian things, they're not baseball cards. Their purpose is to be played, not to sit on a shelf with 50 other snare drums that get played in the home once every five years.
To each their own of course. People often collect things because it brings them joy, and I think that's wonderful. But as a working drummer who loves restoring old drums, I think it's awesome that the market is down. If the big time collectors have gotten out and it's just the players left, that's just fine by me. There's still money to be made in the short term by finding deals and fixing drums, anyway.
