What's the best comic shop in NY? (Or promote the creator of Mona Lisa Ludatits)

So the guy who drew Mona Lisa Ludatits (hereinforth to be referred to as "Ramtha the spirit warrior") has some small comics (a computer-generated book and some minis) that he wants me to sell in NY. If you're interested, here are some of them: http://www.idea-bot.com/gycvo/

Any advice where? I'm thinking Saint Mark's Bookshop (to capitalize on the hipster market!), Midtown Comics, and Forbidden Planet. Any other suggestions?

(And/or, he asked more brazenly, do you want to be an agent of his and sell stuff in your neighborhood?)
