Hi low,
When you say "Lantern style" are you talking about a rocker tool post?
(sometimes there is an east coast / left coast gap in terminology)
the advantage to quick change is that you can set up multiple turning or form tools and switch out with out resetting center hight
or when coupled with a DRO using tool offsets and maintain a true position
(Shooting Star makes an affordable DRO, but the best is Newall)
