I'd personally go with a Bosch ReaXX before a Sawstop.
From what I have read I think its detection/breaking system is superior [plus it doesn't destroy the blade]. Don't care for the self aggrandizing antics of the Sawstop maker either. Don't think its on the market yet, should be any day now [though sawstop has once again recently sued Bosch to snuff competition, not sure how that turned out or if thats a factor in it not being on the market yet]. They said late last year it was slated for a fall 2015 release ,,, Its fall 2015, so we'll see.

Worth noting that most table saw injuries are due to kickback, and of course "sawstop" technology won't help any with that, so that should always bear in mind when operating any saw.
