I was thinking about subscribing to Digital Machinist as they advertise it as being about CNC. I am primarily a wood router kinda CNC'er, but would like to do some light aluminum sometime.

I was wondering if anyone else subscribes, and if so, what they think of the magazine. How relevant are the articles to routing? Are there any back issues of interest? I did look at their website, but I really can't tell from that.
TIA,
