That's an excellent deal from Grizzly Virgil. It is the same saw as DW only makes one which is the DW 788. You see that designation in the Griz advertisement along with their stocking numbers. BTW.. if you want premium blades consider Flying Dutchman. You can find them by Googling Mike's Workshop. Give Mike a call as he knows scroll sawing and he carries premium blades in the Flying Dutchman.
BTW.. if you call ask questions as he will talk to you as long as you want to talk about scroll saws and blades.
Good luck...
