"it is certainly worth far more than an S3 2000"?
OK, but minus the collectible box that's $1634 for body w/ f2 lens, and I still don't get it, unless there's something more unusual about the camera than I (as a user-not-collector) could tell. CameraWest has one in about the same condition as the ad describes for $1200 with f1.4.
The S3 2000 is a great camera but it's a reissue while the 1958 S3 is the real McCoy.
I would trust the newer model because it is less old.
Goodwill go some bad advice, probably from someone who confused the camera with an S3 2000.
The re-issue models are great if you intend to use them (the horror, the horror), but if you are a collector, I guess the 1958 is the read deal.
