I didn't make a statement of the quality of Chinese engines. Though since you mention it I consider them good but not as good as most American and European engines. If you stick to American then if you want top quality you can get Jett which is about the best you can get. For less you can get K&B and Fox. But for a 45 I think you are stuck with Fox (not really stuck they make a very good .45 and .46). Maybe Jett has a 45, I know they have a .50 but not sure about a 45.

European engines? Since Webra is shut down you are stuck with Rossi, Novi Rossi, and MVVS. Not sure what is actually available right now though.

Ihad bought a few ASP and Magnums when Ithought the free trade would bring them around to capitalism, but that no longer seems to be working. I have had good service from them but have had an issue with a soft aluminum casting on a carb which broke too easily, and a brittle steel on a carb barrel. Not a big enoughof a problem to get rid of them, mind you. Ihave never had the same issue with my other engines.

I should have mentioned engines from other Asian countries which are not communist. Of course OS is very good, I just consider them overpriced for what you get. Then there is Saito and Thunder Tiger. I am sure there are others, but they don't come to mind right now.
