I've been wanting a Ludwig Black Beauty for some time now, but I'm reluctant to pony up $600 for a new one. As I've been perusing eBay, I've noticed there seems to be a lot of "B-Stock" Black Beauties out there. In some cases, I think this is not disclosed by the seller. I think Ludwig is putting blue/olive badges on the B-stocks to distinguish them from the A-stocks. Is that true? Also, has anyone bought one of these B-stock Black Beauties? If so, how is it?
