This will kill off the cheap table saw. It will be interesting to see how the hobby and industry adapt to $700 being the bar to entry — and that would be RYOBI grade stuff. The added cost isn’t from the mechanism, the cost is from needing to build a real frame around the blade instead of plastic and thin aluminum. The SawStop trigger is incredibly violent, the braking force will sheer the carbide tips off the saw blade from inertia alone. Cheap saws are almost all plastic and would be horribly deformed after a trigger.
I anticipate a return of something that used to be more common, the upside-down circular saw bolted to a table top.
