If you are going to go "higher end" AK you might as well go with the AR if you don't already have one.
This is not a time to be optimistic about supplies of anything that is dependent on Govt permission, like cheap imported ammo. Domestic sources of reloadable .223/5.56 are far more extensive than the 7.62X39 because with so much cheap steel cased coming in it was not profitable to produce large quantities.
