Check the ways. The 10 x 24 Jet we had didn't have hardened ways
and wore pretty bad, especially near the headstock. It also had a bad
chatter when parting, mostly because it was too light in the carriage
and cross slide.
I later bought a 12 x 36 Shun Shin lathe, also Taiwanese, and
it was a much nicer machine. Its only flaw was the use of a single key
between the drive gear and spindle, and it wore somewhat and would
clunk on startup. The geared head was handy, as was the Camlock
spindle.
