I'm not a huge collector anymore but this is a place I would have gone hog-wild in about 15-20 years ago. There aren't any bells and whistles in there, but Nick has a great selection and collection of collectibles for all.
Nick is a great guy who knows his stuff and spins a good yarn. He's a talker, but if you're in there to see/buy collectibles, you likely have just as many stories to share as him.
