qualification: "really what im looking for is full metal no ugly plastic tip built like a nail for around 600-700 bucks"
For that price you can get something very nice. You should have nothing to worry about. These guys can point you in the right direction. I read a lot of their shit before buying a gun too and it helped. Love my KWA!
The orange tip...you gotta be careful because like in my case, although I already knew it, the gun is displayed with a black tip but shipped with an orange one. If you get one with an orange tip my suggestion would be to search the forums for ways to modify it. There's a few simple methods talked about here.
edit: not all orange tips are plastic. In my case it's painted on to a "metal" (whatever that means) flashhider
