They already haveI personally don't think they will appreciate much, but folks here follow this stuff more closely than I do. I am not a collector. The only thing I know is a real rarity and collectible drum is the original Ludwig Black Beauty. When I ordered my Carolina Drumworks Bubinga snare, Jeff Hankin told me Bubinga is not an endangered species, it's just on the "watch list" as he called it. Countries like China are grabbing all they can get. Other types of Rosewood are much harder to get than Bubinga. Only time will tell. But I agree, there is no "rare, exotic, grail Tama kit.......or any bubinga kit to date".
