Yes, It is. I just got a crack at a newer Rockwell unit with a quick change gear box, thread cutting dial and variable speed drive. I've heard parts are murder to to come by, though, and it needs a few little things to get ship-shape. I'm trying to decide what to do -- get the old South Bend, or go with a the newer unit and hope parts are available. The PO never used it for cutting threads, so the quick change gearbox needs help. Some of the bushings are a bit loose and it's missing a plunger that holds one of the gearsets engaged.
I have until noon tomorrow to make up my mind...
