this is no replacement for a SS, but I was seriously considering this system as some extra insurance with the table saw.
Tricky Cuts on a Table Saw - Micro Jig GRR-Ripper
I have a PM66 and have two of the Grippers. I think the Grippers are a far more useful safety feature then the Saw Stop. While I do like that the Saw Stop makes it near impossible to cut yourself, I do not plan on making any cuts that my hands are anywhere near the blade. Unless the Grippers have a catastrophic failure, I should be good. The Grippers take getting use to, but once you implement them in your routine, you will find that you wondered how you got by safely before them.
I looked at the PM66, PM2000, and the Saw Stop when I upgraded a few years ago. I originally ordered the PM2000 (due to all the extras that came with it), but it arrived all messed up because of the shipping company and I denied shipment. They could not unscrew their shipping company, so I went shopping again.
I ended up with the PM66, because it was on close out on Amazon and I could not beat the price. That is the only reason.
I really could not find a major difference amongst the three aside from SS safety mechanism. Sure there are things like the casters on the PM2000 and blade guard DC thing on the SS, but none of that really matters when you come down to it. For me, I am not moving my saw, so mobility was not an issue. Also, I planned on having a overhead dust collector on it, no matter what saw I ended up with. Reality for me was that all three saws are basically equal when it comes down to how they are built and what they do, which is cut wood.
The two things about SS that concerns me are:
The cost of replacing the mechanism and blades. I have heard about the mechanisms going off without touching the blade, but I do not know if that happens alot or is true.
The other thing that I have never heard addressed is that when the mechanism goes off, how does it effect the frame of the saw. All the torque from stopping the blade, must do something to the saw. If it goes off accidentally or for real, a few times in the life of the saw, what are the stresses on the trunnions and other parts?
Currently, the PM66 with a Incra fence and two Grippers have worked great for me. I can not think of one thing I would like on it, wish I would change or add that the other saws offer.
Again, I recommend the Grippers for any saw that is bought. Those things are great and add such a piece of mind when I am using the TS.
