just to react to one piece of this commentary - every high end lathe I am
familiar with is belt driven - that includes Axminster, Oneway, Stubby,
Nichols, and so on - I guess I don't understand then, with one NZ company
making a "stepper motor" driven lathe, how that means that "everyone has
made their decision" - did I misunderstand?

Not many pulley-driven lathes available any more. Everyone else has
made their decision, now it's time for Teknatool to do it.

Look at market share of the step pulley types are out there.
Then tell me how many have come on the market in the last five years.

Now do you understand?

Yep,
Seems like the Reeves drive is the new default drive system. However, it is
limited in it's speed ranges ( usually approx 500-2000 RPM) unless you also
have some step drive pulleys and belts to use in conjunction with it. But
putting a jack shaft into a Reeves system would be a real bear to engineer,
especially if it's a swivel head.
