Hmm, is there a Stumpjumper Comp disc? I though there was just Stumpjumper with rim brakes, the women design and the Stumpjumper with discs which is 1600$ (maybe this is what you mean?).
You may also want to look at the Trek 8000, its 1500$ and looks like a very nice light bike, complete with a ZR9000 frame, RockShox Reba fork and overall light selection of parts, I like how Treks ride for XC.
The Stumpy looks really nice too.
