I have the Grizzly G0632 which is a kissin' cousin to the 1642. It is a 1 1/2hp, 20V. I rarely have to change belts and, right now, don't even know if it is on high or low range.
Do check out Grizzly, you might be able to save some money. Or get bigger and better for same money. Check out the new G0733 from Griz. A real heavy duty lathe at about 1/2 the price as some of the similar 'name brands'.
