I think that a large majority are just "equipment queers". When there is nothing left to buy they move on. You see this with guitars and computers and woodworking. When those "eq's" see or find out how much work is necessary they suddenly move on. Not an uncommon sight. I bought a lot of high end darkroom stuff cheap because the guy wanted to buy more and different toys. The sad part was he does have some talent but somehow decided that his digi stuff was better than his Leicas. Go figure!!
