A bit off-topic, but other than NYC, what are good cities for this kind of shopping? I remember Boston not being all that great for it, myself, though it's a nice place to visit regardless.
I remember one particularly AWESOME collectible store in Seoul back when I was teaching English in Korea... It was near the Olympic Park, but I can't remember its name. I imagine Tokyo and Hong Kong are pretty good too.
Silver Snail in Toronto is great, but I don't like Canadian pricing.
We should start a thread for awesome toy/collectible stores and cities...
