It tends to be carried at most comic book stores/indie book sellers in the Bay Area, but then again, he's local to there, so you may have more trouble locating current issues.
There's also an omnibus edition purchasable online from lookout records that I can recommend. (amazon has it for ten bucks, but i encourage you to support lookout if you can.)
