Well, you are lucky in that you're choices are pretty limited :). Unless I am sadly mistaken, the only complete ak-74 clones ever imported into the US were romanian - WUM-2, ROMAK-2, SAR-2. The first two being all import parts with thumbhole stock, the SAR-2 being the most current and uses a US parts kit so it can have the PG. The first two were only really imported in limited quantities - it seems there were lots of SAR-2's, but recently the supply seems to have dried up. I have heard that the fit and finish of the WUM-2 and ROMAK-2 were a bit better than the SAR-2, however. SAR-2's could be found for $230 wholesale about 6 months ago, but now all the big distributors are out of them. Any of the other AK-74 clones being sold (like from tenessee guns, for example), are just prettied up SAR-2's.
All AK-74's use a stamped receiver.
