Last Tuesday, I mentioned to one of the guys at the shop I work for that I was looking for a table saw. He said they still had the saws that they replaced with SawStops and were going to sell them.
I'll condense our discussions down to the deal the owner offered me.
They use hydraulic motors to run their saws. He thinks he sold the motors from the old saws, but he does still have the SawStop motors. I am going to buy a 20 year old Grizzly 1023 with a never used 3hp SawStop motor, and a long homemade fence and extra long (6 feet to the right of the blade) rails for $300. He told me to take it, get it put together, and use it before I pay for it to be sure everything still works good.
They were using this saw and fence every day in their shop and only replaced it with the SawStop after one of the boys got some fingers in the blade. It has some surface rust, but everything looks and feels in good shape.
They also have a 15 year old pm66 that I get first chance at if one of the boys don't want it. I would have to find a motor for it if I bought it.
