I recently purchased a TSL-800D from the original owner. It came with a (slightly more than) complete set of change gears. The owner, a machine shop owner/operator, did not really do the best job of preventive maintenance...the apron oiler was inoperative, the tailstock was stuck in a slightly off position, and there is a slight headstock misalignment. The power longitudinal feed shutoff was frozen solid, had been for years it looked like. Fortunately, all that was fixable with no new parts. It's an impressive lathe, smooth to operate and makes parting off actually fun, compared to my old lathe.
It's built like a little brick house. Brake works instantly, tailstock and compound have a good amount of travel, so I'm happy. Surprisingly, another local in my small town also has the same lathe, that he bought new, and he loaned me a 4 jaw chuck. (What are the odds?)
