TLR's seem like the best "bang for buck" entry into medium format. Right now I've kinda decided on a Yashicamat (specifically a 12 or 24). The camera will probably be mainly used for landscapes and portraits. What should I be looking for when buying a used Yashicamat (I'm not too sure about prices either)? And are there any problems I should be looking for if I find a local deal? And also are there any better alternatives for landscapes and portraits that cost under $100?
