I don't think $100 is worth it. Yes you can buy new lenses but Foose Gascan lenses are signature etched lenses. I would wait and keep an eye open for a nicer pair. I did and got them bnib for $145. I bid and watched several pair but I only would get them if they were bnib. If you are getting them because you like the frame and don't care about the lenses being scratched or missing the other stuff, I would say $50-$65 would be the max I would spend for them. Just my 2 cents....
