I've been looking to get into medium format and this camera really caught my eye. I fell in love with it as soon as I saw it. I don't really know much about medium format cameras so I figured I should start asking. Are the LM's hard to find? What should I expect to pay for one in pristine condition (both mechanically and cosmetically)? Are there any quirks about the camera or frequent problems with it? What kind of maintenance should be done to keep it in good condition?
