The Golem's current favorite comic is 2000 AD - an exciting title from Britain - which has published 1600-something issues weekly (more or less) since 1977. It's the comic that gave the world Judge Dredd.
It has been difficult for me to find in the states. I was able to pick up a few while visiting Glasgow in 2005 - and was impressed with the sophisticated storytelling and artwork - kind of like Heavy Metal (the magazine) in it's day, only much more fun.
Am happy to report you can now download the comics (in PDF format) from a website called Clickwheel.net. (It's a good deal too - cheaper than the imported issues would sell for in comic shops).
I'm going to especially recommend 2000 AD Origins - a free download which reprints the first appearances of comic favorites Judge Dredd, Strontium Dog, Halo Jones and many others.
