I received mine last week and very happy with it. Sure, there is room for improvement - a power clip that doesn't have to be screwed in and a trigger that doesn't do anything (how difficult would it have been to have the trigger work a light on the gun barrel?) etc - but this was always sold as a display piece, not a working costume prop. The build quality on mine is very good with the casting very crisp. Sure, you could have made the main body from metal but how would that greatly improve the prop? It would make it overly heavy to wear with a costume and externally it would make no difference at all as the paint job would cover it. Certainly some of the chrome painted parts would be improved by being proper metal but that's just a small niggle as there's only a few on the prop. So, as a display piece, I think it's excellent. As to the $500 price tag, I'm not going there. As with everything, it's worth whatever you're willing to pay for it.
