Johan ingles-le Nobel is, in my opinion, the most knowledgeable photographer on focus stacking and macro rails.
This link is an article on the three best options for automated focusing rails:

Very interesting article. I was not familiar with the MJKZZ product at all, looks like a major competitor.
I totally agree about Johan. His knowledge seems encyclopedic.
There are some great tables on both of these sites. No need for me to tax my math brain.

I would add Helicon to your reading list. Remote allows you to control both your camera and the Stackshot rails and Focus assembles the stack for you.
