If you join the AR15.com site Atlantic will give you a $30 discount on AK's. Their pricing and selection is good. AK pricing is slowly droping now so its a good time to think about buying. Skip the WASR's and get a quality build.

The best deal going now is the basic (sporting) Saiga from Centerfire Systems $299. You can convert the rifle to true AK config yourself easily and have a quality AK for less than $450.

I know AK's and this one is a very good quality build.
I have been shooting both AR and AK platforms for years and own several examples of each and now days the AK would be my go to gun if the SHTF.
