Thought I would briefly revive this thread with my own testimonial:
I've just had my first experience with Igor's Camera Exchange, and I'm very pleased. I bought three items listed on his website: an M6, an R6, and a Zeiss lens. The gear arrived only 36 hours after I placed my order (!), and Igor included a surprise (a copy of Leica Reflex Photography.) All the gear was exactly as described, and fairly priced. A very satisfying and pleasant experience all around. I hope to buy more from Igor in the future.
