Easy answer to the original question "one company, all your stationary woodworking power tools"......As far as I know, only one company listed sells ALL the stationary tools I have in my shop.
Grizzly
PS: In real time, like now...I have never owned a Grizzly tool, but I actually am considering a 623 sliding table saw.
What I actually own, like so many others, is a broad mix. Sawstop, Delta Unisaw/ edge sander/ shaper/drill press/jointer, Castle, DeWalt RAS, Woodmaster, Jet spindle sander, SuperShop, Craftsman.
