Roland,
There are several excellent modeling magazines, some are even available online. While I had subscriptions over the years to some, I have none now. As others have already mentioned there is basically nothing you'll find in any magazine that you won't find here, or on some of the other well known modeling sites.
Every printed article needs to fit a size format, and there is naturally a limit to the number and size of photographs per article. Neither is true with a specialized online forum. Actually, the opposite is often the case. What's more you can ask questions, offer comments, and suggest other ideas and techniques. You're able to have a give and take with the builder and whom ever posts in that thread. And for the most part, it's free.
As I said earlier, many magazines are now going to an online format, but still charge for their content at a reduced rate. If you still want to check out some of the better modeling magazines, you can google them online, or try some book stores like Barnes and Noble here in the States, which carries a large number of magazines, and actually lets you read them there like a mini library.
