There was recently a post mentioning a really high quality focusing rail, but I lost track of that. So, can I get some suggestions for a really good rail, if price is not a concern? I think the rail mentioned ran about $500.

RRS did make one close to that price
I tried to purchase one from B&H after a long wait on back order I was told they were discontinued

I've been using this one (only $100) for a few years now including on my DIY autostepper:

This one is claimed to have very high precision: https://www.amazon.com/SWEBO-LS-001-Screw-Focusing-Accuracy/dp/B07VN3LH16/ref=sr_1_51?dchild=1&keywords=focusing+rail&qid=1625493205&sr=8-51. But I have no experience on the matter.
By high quality do you mean high precision - as in being able to move in very small sub-millimeter increments without lateral movements? Those are appropriate for focus stacking on very small objects at greater than 1:1.
Of course there are the automated kinds made by WeMacro: https://www.wemacro.com

I purchased a Swebo extremely well made no creep in adjustment Is as good as other products I purchased from RRS
No benefit from early shipping
Have used this for a couple of years

What is nice about those kinds of rails (also true for less-precise rails) is you can stack one on another so you have both X and Y axis movement. It makes sense to use a less-precise one (faster moving and cheaper) for moving from side to side.

Thanks, all, for your input. so far, these are not the one I remembered from a week or two ago.

It seems it has to be automated at that price. So maybe

But this one is $500.

I have this SWEBO unit and can't imagine there can be a better manual focus rail made. The cost was more like $200. I have used it with my 4.5X macro lens using 0.05 mm increments at f2.0 and it works fine. The way it's designed keeps the distance from the tripod head to the camera within an inch or so, making it very stable.

I use the WeMacro motorized digital focus rail which sells for $299 and I find it to be excellent. I have over 275,000 shots on it with never as much as a hiccup.

Wemacro rail is indeed very nice. I also have the Sunwayfoto rail it is nicely made but I don't use it for stacking.

I find the 4 direction rail such a help in setting up the first macro shot both when shooting an individual image and moving on with a stack image.
I started with an inexpensive 4 way ($30) and now stack it on top of a more precise 2 direction rail - dang macro is fun.
