Easily Ebay ... unbeatable selection, and only takes a little common sense to find real deals. There's been a couple of bad deals, but I got my money back without hassle in each case. Local shops don't want to know you if you if aren't dropping hundreds of dollars every visit; they really cater to investors, not collectors. Shows work out to be the same kind of deal. I'd consider buying here, but don't have 50 posts.
