A sSawStop is a top quality saw. If you've never seen one, go check it out at Klingspor. Essentially, you're paying ~$1000 premium over a saw like a PM2000 for the safety feature. Is that worth it? I guess it depends on many factors. For someone just starting out in this hobby, that's an awful lot of money to spend on a single tool. For that kind of money, you can get a Grizzly cabinet saw, 6" jointer, DeWalt 735 planer, drill press, router and a bunch of accessories. But, if you have an established shop and you're looking to upgrade for both the quality and the brake, it's not an insurmountable figure...we're not talking about a 12" Euro slider here.
I plan to do woodworking for another 40 years, at least, I hope I'll be able to, but considering how many geezers hang out here, that's a pretty good bet :rolf: Translated, that's a $25 insurance/ year. Is that worth it? I don't think I'll ever have a table saw accident when I'm paying attention. I spend quite a bit of time making sure the outfeed table is clean, featherboards are in place, use a splitter, push sticks/ grippers are nearby etc. But sometimes my mind wanders. Ever make box joints? It's mind numbing. My mind was already halfway into assembly when I realized how dangerous this was, I had come very close to swapping one board for another with the blade spinning less than 1/8" away from my fingers. I shut off the saw and took a 20 minute break. It's for those moment the brake would be valuable. Plus, I'm cheap
I'd hate to ruin a blade and have to buy a new cartridge, so that would force me to be DOUBLE safe
There have been arguments that people would work less safely because of the brake technology. As Colonel Potter would say: Horsehocky! I am willing to bet that if you went to every SawStop owner and asked them to put their fingers into the spinning blade, they'd say no. Even if you offered them $250 (plus the cost of the brake/ cartridge). Just because my car has airbags doesn't mean I'm using trees instead of the brake either.
I think it's great we have a choice to get this safety feature, and I don't understand the controversy. Unless you do this for a living, every dollar you spend on woodworking is basically "unnecessary". We all value different things. Some people happily spend $25,000/ year on hitting a ball with a stick. Others feel compelled to go beyond Norm's fashion line and buy Armani suits, silk shirts and crocodile leather belts. Some go on exotic trips around the world, and others convert their bathroom into a luxury spa with sauna. Me, I splurge on coffee and tools.
