While I can’t speak for other Premium line models, when I play my 7vpwh, my 7VWH, and my PIA back to back, there really is no perceptible difference. I had it PLEKD by SweetWater and I also took it apart and refined issues with fit and finish. When I got my PIA, guess what? It also had to be taken apart and little refinements done here and there to make it truly play like butter. The only obvious and noticeable difference I could see was the Indo paint job was sloppy and you can see the wood grain through the paint. But I have seen some sloppy PIA paint jobs as well. I’d absolutely buy a 7VPWH again. For the price, they are unbeatable.Aha, a new Premium VWH owner, you'll have to tell us how it is!
There are several sellers on flea bay who offer replacement plastics for Jems/RGs, you should be able to find what you're looking for.
