Dave,
From what I've seen, most of the magazines on coffee seem to be trade or business magazines.
Since you're new to the world of coffee, you may want to consider buying a book or two that explains the in's and out's. There are alot of inexpensive books that have more information than you'd find in a magazine.
If you go to a book website such as Amazon.com or Barnes and Noble, etc. and type coffee or espresso into the search field, you will see an extensive list of books.
There is a book entitled "Espresso: Ultimate Coffee" by Kenneth Davids that's not too expensive. It explains the world of coffee, and it goes into detail for the home user. I bought it as a gift for a friend, and she loves it.
