Gary, as someone who owns both a Sawstop cabinet saw (professional 3 hp) and a Bosch Reaxx that also has the flesh detecting electronics, I would definitely recommend the Bosch. Of course they are 2 different saws, one is a cabinet, and the Bosch is a contractor size and grade. However, I had a really bad experience with the Sawstop. I was cutting some dados into western red cedar and had a brake cartridge activation. It of course destroyed the $75 brake cartridge as its designed to, but also a $150 dado set, which I suppose is better than your fingers (the activation was set off by the wood, not my fingers).
However, the Bosch doesn't destroy the blade, and it only sets you back about $45 for an activation. Its also a lot faster to recover as the blade on the Sawstop gets jammed onto the arbor with its activation. I use an Incra miter gage on both saws... If you have the choice to compare the Sawstop contractor and Reaxx, I think you will like the Reaxx better.
I sent in the brake cartridge to Sawstop to determine what happened and they said it was activated due to cutting into pressure treated wood. I am not a genius, but I know what I was cutting and can tell the difference between PT and WRC. The real kicker was that the technician said they had reports of WRC causing activations, and I told him it would have been really nice to be warned about that like they warn about PT. This poor customer service really gave me a negative attitude about them as IMHO they are very arrogant. Of course, this is my opinion so please make the best choice for you. David
