I don't want to start something here. Well.....yes..I do.
Ennyehow, I got in a friendly PM exchange with a member who is selling a used Jet 16-42 lathe. I declined his offer as too high for used and because I could buy the identical G0632 item from Grizzly, new, for about the same money. He responded that he had looked into the Griz and found features inferior to the Jet. Well, OK, I suppose that's possible. He said the bed on the Griz was steel and not cast iron like the Jet. That raised my curiosity because I visit the Grizzly store half a dozen times a year and have never seen a steel bed lathe there. And, even, my entry level $325.00 (at the time) Grizzly G1067Z has a great cast iron bed on it. I wrote to Jet customer service. The reply from and Aundrea said, "(the Grizzly has a steel bed)." A similar request to, and from, Grizzly said, "The bed of the G0632 is made of precision-ground cast iron."
No other features that might distinguish one from the other could be identified. Jet did say theirs had an indexing head and Grizzly didn't. The Grizzly does have an indexing head. I am distressed that the Jet rep. would state outright lies and wrongfully knock a competitor in that manner. For several hundred dollars less, relatively local pick-up for me and previous excellent good customer service experience, I'll be going with the Grizzly. If I get full price for my tractor (that's where the lathe funds are coming from), I have been considering also getting a Jet Mini VS. Now, I'm going to explore other brands first.
