Definitely a good time time upgrade Bandsaws. I think the lawyers and media event surrounding the Jet vs Grizzly color hoohah will only get Grizzly free advertizing.
I believe it is a separate brand, but closely associated with Grizzly. I've heard that both companies share common ownership. ShopFox is a brand meant to be sold in retail outlets rather than direct-mail (Grizzly). However, some models are also available direct from Grizzly. The ShopFox models tend to be very similar in design to Grizzly modes, frequently they would be the higher-end models in the Grizzly line-up.
