Your Image favorites are good ones, NKino. I would add Gideon Falls, Death or Glory, Infidel, and Days of Hate. I'm not as obsessive as some, but I'm still buying about 15 comics per week, plus a lot of graphic novels, compilations, and artist editions. My rule of thumb is "no Marvel or DC".
I'm a huge fan of European albums, and there is a ridiculous amount of stuff out there worth acquiring. My fav publishers are Cinebook, Europe Comics (all digital), and Delcourt/Soleil. IDW's Eurocomics brand has issued stunning work. Lion Forge is putting great material out, and Amigo Comics is really good too. not to mention NBM, Fantagraphics, and Drawn and Quarterly.
The American market for comics has always been wound around super-heroes. Currently, with all the relaunches and devastation to character continuity, I just can't abide the shameless multi-covered marketing designed to grab market share. The Batman #50 debacle was a horrible abuse heaped on the fans of super-hero comics. Then there's DC's Wal-Mart comics selling for absurd amounts on eBay.
I feel like a pariah in a comic shop. Super-heroes are a comics shop's raison d'etre, and all I'm interested in is what they have on their racks that's not that. I drive my guy nuts with all my special orders and product questions. But they are good folks and tolerate my quirks.
But I'll tell you what--I've been in an amazing amount of comic shops around the country and I very rarely see a shop aggressively marketing new, non super-hero product. It's like they acknowledge quality products, but still regress to the same old same old.
I'm glad your enjoying Image. I believe the best comics that have ever been done are being done right now.
