OK, I can't resist. Here are a few of mine.
The key point for me is that these are all still regular users for me. I bought the Salut in a Moscow pawn shop a few years ago, and it is fun to use with that 2.8/80 lens, and the brass shutter sounds like someone is sword-fighting. :Wow1:
The Seagull TLR is one I bought in Beijing in a camera shop, it has a great lens, similar feel to a Tessar when you shoot with it. It is a 1:3.5/75 which does nice low light landscapes.
And the Balda-Baldix bellows actually was my grandfather's. He used it when he was a professional photographer in the Yukon in the 1950s. It has a very german period lens, crisp and uncoated. Also a 1:3.5, it has the shutter in the lens itself which is pretty cool. When I got it all I needed to do to it was touch up the flocking. Even the timing was spot on.
The light meter is actually a selenium meter. It doesn't use batteries. It isn't super accurate unless you recalibrate it all the time, but it always brings a smile when you show people how it works.
