My understanding is that grizzly and Laguna are made in the same factory. Maybe different companies, but same trunnions, cabinets, parts, etc. The Laguna has a few extras added, but terrible documentation and customer service. Grizzly customer service appears to be top notch as well as the documentation.
Sawstop- hate the owners attempts at using government to force his product on all of us. That said, by most accounts, a fantastic saw.
