I do not recommend Eide's in Pittsburgh, even if they claim to be the World's Greatest Comic Store.
I can't recall a single time that I've left that store where I didn't feel offended by the narcissism and just plain rudeness from all but maybe one of the "Comic book guys".
Maybe if I dropped a few grand on their over-priced golden aged books, they'd be a bit nicer. I live in Pittsburgh, work a 5 minute walk from them, but will never go there again until I hear the day they fire all of their long-term employees and actually get some decent, nice people.
I love that they bad-mouth New Dimension Comics, and now 5 stores later, I can guarantee you that NDC is more respected and enjoyed by comic fans. Eides had a 15 year head start to build up a golden/silver collection, but they are juts a bunch of a-holes.
