Battles Magazine is now offering all their back issues for 5€ apiece in PDF. I purchased the first issue in paper for about $25 at the time and thought it was a really well put-together magazine. (They run 35€ now plus shipping. Salty, but this is a thick mag . . . runs 150 pages or so.) Good writing, from a broad array of historians and gamers.
The pdf versions will not come with images of the game pieces that the paper version included, but for 80% off it's worth a look if you're interested in the genre.
