HI Chris, welcome.
There's nothing which is really perfect, off the shelf, for all situations.
This thread on Bellows and Rails http://www.photomacrography.net/forum/v ... php?t=8411
will be a start.
The ones you've suggested look very good quality, I expect either would be fine for the lower end of the 1x - 5x magnification range your lens can do. One or two members here have them.
An important thing is the step size you'll need for stacking. At 1x it'll be about 1mm; at 2x 0.125mm; and at the 5x end perhaps 0.020 mm, = 20 microns.
The threads on those RRS/Hejnar rails are just over 1mm per turn, which gets to be difficult at the 5x end. There are no markings on the knobs?
Micrometer-driven rails are generally on very smooth ball-bearing tracks, with the micrometer itself having 10 micron smallest graduations.
Rails of that type are made by Newport, Parker, Kohzu and several others, but DON'T come with anything designed for fixing to a camera or tripod. The normal/best route to go is to attach "Arca" type clamps, as you find from RRS, Hejnar and others. You'll need basic metal-working facilities to drill holes for screws, etc.
Another option, for a motorized rail, is the "Stackshot", which you'll find widely mentioned here.

To use a classic quote from 'Antz' - "I almost know exactly what I'm doing!"
. I've considered them before but they always seem too expensive new for what they give. I have an old one which has worn too sloppy.
