If the handles arent broken it is a good price, If it includes the gear set its a better deal.`
check the jaw function for smoothness and to make sure all three jaws clamp evenly at the same time. I have had chuck that gripped in the back and not out at the front. look for easy or even sloppy movement of the carriage at the front by the chuck and tight dragging back at the tailstock. This checks for excessive wear on the ways.
Its easy to adjust the carriage if its a little to loose the whole way.
