The S3-2000 in chrome, with the "Millenium" 50mm F1.4 Nikkor is the one to get. The lens is the best 50mm lens ever made by Nikon. Get the camera in chrome, the price on the used market is not much more than a vintage camera in similar condition. The viewfinder prisms are going to be in better condition than the 60 year old originals. These were ~$4500 when new in 2001 or so. Prices are at a bargain these days. An Olympic Nikkor 50/1.4 would cost more than the S3-2000 with "Millenium" Nikkor.
The Nikon SP-2005 has held a premium, but far fewer were made, and it was only available in Black.
I tend to use the 35mm lens on the S3 and a 50 or 85 on the SP.
I have an S3, and the S3-2000. It's not a copy. It is improved in some subtle ways.
