My monthly reads include:
Car <--British mag about cars.
Bike <-- About mountain biking. The photo annuals are great.
Linux Format <-- British mag about Linux.
Computer Music <-- British mag about making music on your computer.
Sports Car International <-- American mag about sports cars. Only bi-monthly.
I have found that the British magazines are usually so much better than what the US puts out. I may pay twice as much for Linux Format compared to other Linux magazine on the shelf but when you look at how much more content is written in them and then the fact that you get a CD or DVD full of software every month you realize that the other magazines are a rip off.
