I've picked up a few copies of Silvershotz magazine, and enjoy looking through most of it. It's an international 'folio type publication rather than an informational based. But they boast that of the 100 pages, there are only 6 that are adverts (I didn't count to verify that).
It does include digital and mixed media, but a good portion (more than half?) is film/analog and alt process.
Subs run $77 for Can/US.
