Delta is getting out of the scrollsaw business. So they are selling their saws at close out prices. The delta saw is almost the exact same saw as the Dewalt 788. The only real difference is the Delta's are blue.
My local Woodcraft has the Delta saw for $349.99, it comes with the stand and a light.
Dewalt bought Delta or the other way around. Either way, it is a good deal if you are in the market for a good mid-priced saw. I have the Dewalt and have been very pleased with it.
