I saw on Craig's List where someone said they had lots of old cameras that they needed to get rid of, so I figured it was up to me to help him. He had some pictures and I spied a couple that I would love to have. I went to his house today, and sure enough he had lots of old cameras. He said he had acquired them from garage sales, etc. They were mostly 35mm rangefinder and slrs but he had 3 120 film cameras that wanted to go home with me. I think his prices were reasonable but I had only taken enough money for two of them so that was what I brought home. Here are pictures of those. One is a 6x6 Bronica S2 and the other a 6x7 Mamiya RB67 professional. They are both in used but decent shape. The Bronica's shutter is not working every time, the Mamiya seems to be all working fine. They weren't cheap, but I am happy with them.
Wow that Mamiya is a beauty. I'm sure there were so many other cameras that you wanted. Craigslist and Gumtree are great but you have to keep looking - all the good stuff is overpriced and anything else gets snappped up.
