I recently bought a Jet 1336 PBD. I paid $1800, but in my area (Montana) decent used metal lathes are difficult to find. I think I probably paid too much, but I'm determined to make it work for me. If the spindle checks out I will soon be testing my theory that the backgear and bull gear from the BDB-1340 are compatible replacements. If you're like me you may wish you waited for old American metal due to parts. The PBD lathes seem to have been very well made and popular. I've not read a bad review; it's just a question of parts. There's no good way to lock the spindle and the chuck screws on; when it's too tight people put the lathe in backgear to hold it so they can unscrew the chuck. That sometimes results in breaking the helical backgear and bull gear.
Based on mine I would check those gears and the change gear functions.
That model has hardened ways, which is good.
