I had a Native, but it was the non-Sustainer model.
It was OK but nothing special. The trem on it could only be used very sparingly or it'd put the guitar out of tune. Also, I had a problem with the high E string jumping out of the nut if I did strings bends. The nut probably needed to be re-cut a bit. I solved that problem by running the string on the inside of the string tree thingy rather than the outside (which is where it was designed to go).
