I'd say Renderosity :) Seriously - great print quality, great variety of topics/programs, cool stuff on the CD. AND you can come here and ask the authors questions - isn't that cool? Aside from the fact that I have an article in Issue 2 :) 3Dworld mag is also good - but frankly I haven't bothered much with magazines since I've been at Rosity - much easier to just go bug people in the forums :)
