Yes, but there are all kinds of mishaps that can lead to all kinds of accidents. SawStop helps prevent basically one sort.
Some people mentioned accidents with a TS blade even though the blade wasn't moving. Are these the result of reaching across the blade or falling on it in some way? I honestly never considered those possibilities.
The salesman at Woodcraft say that the Sawstop is better than the Unisaw even without the safety features. BTW, the "industrial model" (30" wide table) is $4500, and the "professional model" (w/27" table) is closer to $2900. Mobile bases are an extra $200, or $300 for the "hydraulic" version. Salesman was not aware of any differences between the industrial and professional models beyond the size of the table and the location of the blade adjustment cranks. At this juncture, I am not seriously considering spending $4500 on a TS anyway. One needs to draw the line somewhere...lol.
