Some other places that I recommend checking out:
Fugscreens Studios – real stand-up guys, and the most reliable screen printing shop I know of.
Screwball Press - a great place to learn and practice the art of screen printing, full of interesting characters.
PosterWhore - a cool blog showcasing poster art from all over.
N-Spheres Art Magazine – an interesting offbeat publication showcasing obscure artists around the world.
