Does anyone know where I can find a simple (cheap) 1.25" filter holder
based on a slide and not rotation

If I knew of an inexpensive one I would probably own it! I've always
wanted one; but found the price to always be a bit unrealistically
high. Also, dew/frost formation on exposed filters has been a
concern.
Your question got me thinking. I recently bought a 'shorty' 2x Barlow
to replace an older, longer, 2x Barlow. I could probably butcher the
older Barlow and make a decent 'quick-change' filter holder out of it.
IOW, if you have suitable parts lying around you might be able to make
your own -- possibly even better than the expensive, manufactured
models!
Instead of a slide I may be able to improvise a slot to drop a filter
into. To change filters I could plop out one filter and plop in a
different filter (various procedural ideas come to mind that I'll need
to narrow down and fine tune). This would still be much more
convenient than removing the eyepiece, unscrewing one filter, screwing
in another and re-inserting the eyepiece.
Such devices would very likely lead to more filter experimentation and
use.
Good luck in your search! Meanwhile I'll see what I can make with I
have on hand ;-)
