I have never seen any data regarding which ZX/MZ models were were manufactured with the failure-prone plastic gear and which, if any, with the revised motor with metal gear.
Please correct me if I'm wrong but I have assumed all models except perhaps the radically different MZ-S are so affected.

I meant function-wise ZX-L is much improved on ZX-7. I believe ZX-L was based on ZX-7 but it improved several areas, including personal functions, spot meter mode, advanced flash support, higher flash sync speed, better grip shape, etc. You may check Bojidar's K mount website to find details. Due to this as well as current low price of both cameras, there is no need to take the hassle to replace motor. Just buy a ZX-L and you will get more of a camera than ZX-7.
I'm not sure whether ZX-L has better motor but some people suggested so.
