Bottom line is get yourself a nice SKS D if you want to spend the $500, or an M model for around $350. Both take any AK mags which are readily available for cheap, and both eat any 7.62x39. Function is as close as you can get to an AK as long as you don't buy one with a beat down gas tube from someone having shot corrosive ammo w/out proper cleaning and you have acceptable accuracy in a rifle design that served several countries all around the world and is still in use today.
With the money you save you can get 2 or 3 cases of 7.62x39!
