You must be thinking of the 16" Jet. The 3K is an order of magnitude
better than either 14". Machining & engineering. Weight alone isn't
everything and any amount can be added. Variable speed is (mostly)
hype. The range on the 3K is more than needed and belt drive doesn't
suffer from low speed torque problems of electronic VS nor the noise
adjustment & cleaning problems of a Reeves drive.
