I've run into a couple of vendors, but they're mostly trash vendors with poor stock and low caps. I figure that Diamond City has a solid collection of better vendors, since it's a major settlement, but I'm wondering if there's somewhere else that also has good vendors; I'm staying away from the main quest at the moment, so if I can find a good vendor without having to hit up Diamond City, that would be great. Is there such a vendor, or should I just bite the bullet and head to Diamond City?
