People don't consider jackets like this based on value, if you think there is a justification for the price other than exclusivity an rareness you are wrong. You pay because you like the way it makes you feel.
Literally this. It's what this is all about. We all often drone our elaborate justifications why buying one of our pricey jackets is worth it when it's really all about how it makes us feel and there's no denying it; Brands do matter and make us feel good - And vintage is a brand, too. Just the other kind of brand.
It's worth it if it's something you really want. You seemed set on one of these & I say go for it.
SB is a good maker. They make a nice, tough jacket that isn't really lagging behind either of the two makers you were originally interested in and honestly, at that price point, you're not really saving much by buying a SB instead of Toys or Head.
