What's a good price to pay for something like this? Is $100 way too much for new but never used? I like the old metal box vintage feel but would I get a better product buying new or just spending more money? Thanks.
$100 isn't a bad deal. The ratchet value has gone down since everyone wants fine tooth now. So thats in your favor. Id offer $75 and negotiate from there. If its a needed tool for you then $100 is fair.
All my tools 99% are all metric, working as a mechanic at Yamaha/Kawasaki shop.
Is it metric?
I like metal boxes like that, everything now is plastic. I bought some metal storage boxes like that were like Proto with piano type hinges. They hold up great.
