most of the camera mags have pages in the back advertising these fairs...
Yes, I agree about the condition of some of the stuff sold. Admittedly, some of my trusted kit looks like it's been driven over, but I wouldn't want to buy it in that condition.
Yeah, the high end stuff has come down too. I was looking at Contax AX and RTS III bodies, absolutely obsurd low prices, considering the prices they were when new....
Although having said this it does help lower prices if the system is 'dead'....take some Canon manual focus FD fit lenses, I'm amazed how some pro lenses fetch such low s/h prices...In contrast, some EF mount (eos) lenses, even some of the basic, dare I say, second rate lenses still fetch silly money
