I have a Norinco MAK 90. The Norinkos are stamped receives but thicker (1.6mm) that other stamped receivers. The Norinkos have a reputation as some of the best made AKs. problem for you is they are going for $2500 to $3000 right now. I paid $250 for my MAK 90 back in '92. They're going for $1500 and up now. Probably the best option would be an SKS which you could buy for around $1000. BTW, the prices will never come down, so if you want something buy it now. Back when Springfield M1A were going for $700 to $800 dollars I dilly dallied around, Then they jumped up to $1200 and they have never come back down. Really nice M-14s like a Fulton Armory or James River Rockola will cost your $2800 - $3000. If you want something, bite the bullet and get it.
