There is a guy around here that has a Voigtlander Prominent II, Ultron 1:2 50mm, Dynaron 1:4.5 100mm, Proximeters, 50mm Turnit, metal hood, cases, flash, and misc... for $500. From the pictures, it looks to be in exceptional condition.
My local reputable camera repair shop has a QL17 GIII that they just did a CLA on. They are backing their work if I buy the camera. They want $90. This might be the way to go for now.
I have one of these and bought it because I thought it was a very interesting design. However, I have never really used it as it is a bit like trying to take pictures with an Imperial Typewriter with a Legal Carriage.
