I have two AR's, one being an Palmetto upper and lower that I built 2 weeks ago, but if the SHTF, I'd grab the WASR first. I've had it for about 4 years, shot tons of rounds thru it, and it never malfunctions, even with hardly ever cleaning it.
I would think it should be pretty easy to get one for around $400 so that leaves $100 for a half a case of ammo.
