I think you are correct about the UV coating.... I got the whole system down to about 20 pops for a 5x7 neg..... But then the light bulb finally went off in my head & I realized that the lighting system might be worth some $$$$. Did a bit of research and these things are still selling for a good price on the auction site.... The quality seems fine.... The stands are even air cushioned and make a very satisfying hissing sound when they are telescoped down. I see from your link that a lot of the accessory equipment has not changed much since my units were made. So it seems I have the potential here to replace my strobe system with a Nuarc and have cash left over for a wee jug of platinum as well!

Thanks for the extra info....... Annie
