I have never herd of "NGS" I have a wacom intos tablet 6x8 inch size, it has 1024 levels of presure, feels good in the hand too. I love it! my 1st one I had for 4 years and beat on it the last year, I just replaced it recently and I love it even more! Just like photoshop is the industry standard and wacom is the industry standard as tablets go, they are verry stable. If you do online price compare you may be able to get your hands on one for $155.00 to $199.00. Hope this helps you: )
