If the Zeta are set up and tuned to run those motors and that load, I'd
stick with them.  If one burns out that's a different story.  There is also
a pulse rate problem that may influence your decision.

IMHO - This 250,000 steps/sec will be a non-starter.   The emc is
advertized to 5k and some folk get 3-5 times that.   Even the thought is
boggling.  Could you describe your machine, motors, gearing, feedback,
and such.
