I had a Polish-made TT-33, similar to the Norinco's you mentioned. It was clunky, didn't point well for me, very heavy trigger pull. I really liked that it was a 7.62X25 but I gave it away after parts started falling off of it at the range. Norinco's are nice (IMO), I have one in a 1911 and it functions well.
I saw a Norinco "TT-33" type in a parts bin in a Pensacola gun store recently...it had a cracked slide and bushing and was rusted solid.
For $409, you can get an excellent turn-in SIG P226 in .357Sig or P229 in .40 S&W from CDNN.
