Pat has been in the comics biz since I was a kid. (I am 50 now) He is more than fair in his pricing, and while his store is a little small, he packs a lot of good stuff into the space he has. He generally has 8-15 dollar boxes, and these aren't junk comics like you find in some dollar boxes. I have found some pretty good stuff in those boxes, and have found some really cool stuff. he is more than willing to pull books for people, discounts his books, and has the best prices of anyone I have seen in the area. (and I have shopped around) I highly recommend this shop for the comic book aficionado.
I have been coming here for a little over a year for my weekly issues. The owner is very nice and will help you with what you need. It may look small on the outside, but they have tons of back-issues, variants, and collections along with a wide variety of ongoing series. Not only do they stock books from major publishers, you can easily find a small-press book as well.
