I recently bought new ones from NPD and was pleasantly surprised at the quality of the chrome and how well they fit. I haven't snapped a top boot to them yet, so I can't speak to how well the snaps are spaced, but otherwise I'm very happy with them.
I sold a new reproduction set on ebay just a couple months back. I had bought them for a car and then didn't use them. I had checked them against the originals and was pleased with the alignment of the holes and the chrome quality was real nice.
