Anything I should know before buying a Micro Seiki RX-5000

Those two MS TTs will be working up to spec when most of us have turned to dust, and beyond. There are two elements that will need attention over time: the belt and the motor, same as any brand new belt drive TT. Check for bearing wear as well but otherwise they consist of two solid chunks of metal that ain’t going anywhere and there are modern motor systems that could replace the original.

lewm are the motors serviceable? 

To the degree that any motor is serviceable I would suppose the MS motors are serviceable. I know nothing about the specifics, but I do also know there are good new commercially available motors that might be suitable.
