I'm considering an AK as well. Here's the website for Russian-American Armory: click on "Distributors" and you'll see a bunch of links.
Atlantic Firearms has a special going on that I'd like to jump on: a Romanian AK with 2 30-round magazines, mag pouch, bayonet, cleaning kit, oiler, and carrying case for $439.
Here's the site for FBMG, Inc. They have some great deals on Saiga rifles, basically Russian-made AK sporters; they can put you in a 7.62 Russian model for under $300.
Good hunting. As soon as I have the $, I'll be joining you...
