The question you have to ask yourself why would you want one??? If it is for the safety of the blade stoppage then it is the saw for you. All the sawstop brand saws are well made. They stand behind them. As far as the trigger mechanism goes there have been instances where they will replace for free but not the blade. Never the blade.
Remember though wet wood, metal will trigger the stop and you must shut it off. being a jobsite saw not sure where you would be using and who would be using. Having the extra safety feature is a plus but hope it does not lead to lax safety procedures. That would be a false sense of safety. They are heavier than most jobsite saws to help dampen vibration. The dust collection on any jobsite saw is bare minimum at best and the sawstop is the least which supposibly they were working on. Then there is the price of the saw plus the price of the brake and the new blade every time you trip it. Never use a blade that has been tripped. Internal cracks can be deadly.
No I do not have one. I do not know of anyone who has the new jobsite saw but i have used and seen the contractors saw and the cabinet saw. Very good quality. I am sure the jobsite one is as well. They are a reputable company.
My opinion I would look at the Bosh but again it is my opinion and also if you are dead set on the braking system then go for it.
