I've owned a couple MAK-90s, and they were the nicest AK variants I've ever shot. I have experience with several Romy AKs, Yugo, Bulgarian, and Maadi, and the Norincos were by far the best quality.
Everyone knows how much I love a Norinco SKS as well. Never shot their M1A clone, but if it is as nice as their AKs and SKSs, I don't think you can go wrong.
