I'd go shopping for a V-GT Luxe.
The nice thing about SunTour derailleurs is that they all perform pretty much the same, and that performance is uniformly excellent. The fancier models will be lighter and better finished, but don't perform better than the lower models. If weight isn't an issue, the steel V-GT or Honor models are also widely available and likely cost less than the aluminum V-GT Luxe.
