The Mitsubishi LT-22 is a Direct Drive, Linear Tracking, quite solid, I recommend it for an easy hands free start/stop setup.
I just listened to my friends again yesterday, I helped him get it/set it up a few years ago, still quite impressive, I have a Vertical version LT-5V which is belt drive, belt arm movement, and LED for arm tracking, works great,.
a belt and an led are involved with the arm’s movement/tracking.
easy to replace the arm’s belt, not so easy to replace the LED, however the LED does not age when just sitting around for years, so if it was not used a great deal, you can expect years of trouble free, just put a new small belt that moves the arm.
