It's been a while since I've posted here and, in fact, I've acquired a few rangefinders in the interim. My most significant recent rangefinder purchases are an Agfa Isolette III 6x6 w/Solinar in a Synchro Compur shutter, and a Zeiss Ikonta 524/16 6x6 w/Tessar in a Synchro Compur shutter. I bought the Agfa Isolette off Goodwill's auction site for about $50, and found the Zeiss Ikonta sitting on the shelf in a second-hand store for $3.93. Woot! Both are outstanding square medium format shooters.
