My 2 favorites are: Quilters Companion (from Australia), and Australian Patchwork & Quilting.
I view Quilters Companion as the top of the line. They publish every 2 or 3 months - but I just drool over each issue. It's a combination of the pattern and accompanying story. Of course tips and tricks too.
An example of its contents can be found here:

AP&Q publish monthly. They are a combination of easy through to challenging quilts. AP&Q example can be found at this address, at the bottom of the page:

I no longer purchase magazines on a regular basis. I have too many now, and need to down size. So... I'm be going through my magazines, removing the patterns I like - then putting them into plastic sleeves in a folder.
Like many my income has been "reprioritized".
I also found that I used the photos in the magazines as inspiration - but you can get lots and lots of inspiration off the web.
Hope that helps.
