I get BYO and Zymurgy for brewing. I also get All About Beer for some general beer stuff and because you find some of the best beer writers in the world published there. I also pick up the Southwest Brewing News and Celebrator when I am at the LHBS or some other place that carries them.
As a CAMRA member, I also get their periodicals, which are good for keeping up with what's going on in at least one other part of the world.
