John, of the two click pens that you yourself mention as candidates for your selection, I MUCH prefer the Luxor.
First let me say that I strongly favor click pens that use the Schmidt SKM-88 click mechanism which is the big plus for the Luxor, IMO.

This reply has become more lengthy than I originally intended.
But I hope you . . . .John (and others) . . . . will continue to read as it concludes with what I believe is a new and exciting development,
brought to us by McKenzie Penworks, namely the all-American stainless steel Coyote Click Pen Kit with Schmidt click mechanism.
Along the way, I describe how I use and modify the Luxor pen kit which, until now at least, has been one of my favorite, and relatively affordable, reliable, and attractive click pen kits which also features the Schmidt click mechanism . . . . . in a more modest design.

The Stratus from PSI does not use the Schmidt SKM-88 click mechanism.
Personally, I do not like this pen, partly for that reason.
Also, I just don't like its looks.
It uses a proprietary PSI click mechanism with an uncertain feel about it.
The Luxor is one of my "go-to" click pens because of its high quality and because it uses the Schmidt SKM-88 click mechanism . . .
. . . but bear this in mind . . .
At first sight, the Luxor doesn't meet one of your criteria in that it has a refill extender which can get lost.
But that little problem can be overcome quite easily and quite quickly.

By way of explanation, first take a look at the instruction sheet for the Luxor Click Pen Kit :
You will see that . . . .
With the Luxor, you can make your own refill extender and glue that onto the SKM-88 mechanism . . . extra work, but this avoids the loss issue.
The replacement extender is quite easy to make from a short piece of aluminum rod.
It's best to make this replacement with an axial hole to fit over the internal SKM-88 shaft and glue it permanently on with epoxy.
The length of the aluminum replacement extender can be just the same as the original plastic extender plus the length by which the hole overlaps the SKM-88 shaft for gluing on.
By making your own refill extender in this way you can even customize the length of the Luxor pen if you wish to do so.
Another way to build the Luxor and avoid the refill extender is to just shorten the 8mm brass tube by an amount equal to the extender length.
Of course, the final resulting pen is shortened by that amount but some people like the slightly shorter pen.
But I prefer to make my Luxors with the permanently installed (glued) aluminum replacement extender rod.
Once you work out your method, the extra time involved is only 5 minutes or less, not counting the time for the glue to set.
I've made lots of Luxors in this way.
After having said all this . . . .
I would be remiss if I did not finally mention the brilliant (but expensive) new Coyote Click Pen Kit by the McKenzie company.
This stainless steel kit uses the SKM-88 mechanism and has a very attractive design.

An IAP member, Dieseldoc, has recently presented an example of this McKenzie Coyote Click Pen here :
Put together one of. McKenzie Pen SS kit called Coyote which includes Schmidt SKM88 push button on 8mm tube with Parker refill. Blank use is from ProKraft UK that was used by. ValleyBoy in his fountain pen positiong. Great looking blank. Interesting when putting the tube in. on first blank...

You would do well to have a look at it. I have not made one, but I applaud McKenzie for bringing this kit to the market.
Thanks to
@Dieseldoc for showing us his work with this kit.
Notice that the Coyote Click Pen Kit does NOT require any refill extender.
Here is a video showing the easy assembly of this new addition to the pen kit inventory that we have access to ! !
