You're best bet right now is a Zastava O-PAP M70. It's a factory built gun in Serbia by Zastava. It's imported into the country with a single stack magazine and no bayonet lug. The magwell is widened out by Century to accept hi-cap mags. It runs about $550-$600. It follows the Yugo M70AB1 pattern. The best part about the rifle is that it has a foreign receiver with an authentic bulged trunnion and hammer forged barrel!
The stamped receiver Arsenals are usually Saigas from Russia, and the milled rifles like the SAM7-R or SLR-101s are Bulgarian. Both feature hammer forged, chrome-lined barrels which are made to last forever. I have a few Arsenals, and they are nice, but too many people drink the Arsenal Koolaid.
The WASR is just a rifle that is brought in as a single stack rifle like the O-PAP, and the magwell is hogged out. People bitch about the WASR series of rifles, but they are good rifles. My favorite AK is my WASR.
The things you want to look for are:
straight sights, gas block, tight magwell, no deformed rivets (stamped only), and I prefer foreign made barrels. They are made to last.

Also, the CAI Yugo M70AB2 underfolders are solid. I have one of those too. Good luck!
