I'm with you on trying to start collecting some quality over quantity. I actually don't own any CGC comics, but I've been considering picking up one or two to start and see where it goes! I'm more drawn to some classic silver age stuff vs. modern variants or signatures though. Those are some beauts you have, they'll look nice displayed.

I'd like my main focus to be original art. In response to your request for comment pics... here's one! (admittedly low quality, just snapped it now...)

Action pages with heroes in costume are a bit out of my price range currently... but you can still scoop up some great artists, and I just love the quality of the lines and the amazing craftsmanship you can see! This is a page of Supreme Power by Gary Frank. I picked it up on eBay for about $50. I've been meaning to post about collecting original art, I'll have to get on that! @kidsysco does a great regular column about original comic art that's always inspiring...

Looking forward to seeing more of your collection!
