There is this greek published magazine that has very high quallity glossy thick pages book-like binding and a bit more than a hundred pages, has about five pages of ads per issue, concentrates on photographs only with a few lines of photographer's biography and costs seven euros per issue. The double edged sword is that it accepts images from any source and aesthetics so it can have anything from classic cliches to experimental garbage. It is published every two months and I always look forward to a copy in the newstand.
The US, BW magazine has good photography and paper but its printing could be better especially since it is aimed at collectors and ends up costing 12 euros an issue.
In other words, I don't think any magazine justifices higher prices than 10 euros/dollars unless is printed and valued as a book.
