The Stage 2 is a Chinese copy of the Stealth.
I have seen pics posted of the Stage 2, right out of the box, and the quality is horrible.
Casting and machine work both were bad.
IMO, it's not worth saving a few bux to get a copy of the Stealth.
My next door neighbor just got his Stealth in from Summit yesterday and the quality is pristine just like every other Stealth I have seen/had.
