Glad to have sparked a pleasant memory or two! I got mine 4 years ago for $155 from a RangeFinderForum member in New York and had it rebuilt by Camera Care for $190, including a new meter cell. That service also included a CLA for the lens, which was $152 from a seller in Kerala India. I don't use the kit very much, but it's fun when I do. :)

I had that same camera ! The first Contax I had I bought in Berlin in 1956 for £38 it was the model III with the un-coated f1.5 Sonnar--not very good-- then I got a IIIa with coated f1.5 Sonnar.
