Over the years... I've found that most mag's don't do anything other than get you into the hype of the sport. Most mag's won't give you a real opinion of an item they test because those companies are paying advertising. So... if they give a ski or part a bad review... that company may pull their advertising $$$.
BUT... if you want to do some readong... I'd say to head over to a place like Barn's and Noble, or Border's books. They have a large mag section, and I'm sure you will find something you like.
