We have a camera show this weekend in DFW. The guy that puts them on does so twice a year. In the 1990s, there were six a year, and each one was 6 - 10 times the size of the two that occur now. Yes, first ebay, then digital has maimed, if not yet killed this phenomenon. One just has to get over it.
On the other hand, at the last one, there was a commercial pro who had shut down his darkroom and brought all the smaller gear (no enlargers) to the show to sell CHEAP. A few of us cleaned up!
