I have come to like the "red-dot" reflex type finders in the last dozen years or so, but still use a 50mm finder and sometimes up to 80mm when finding objects manually. When I finally finish my 17.5" Newt, it will have not only those, but either a 5" or 6" short-focus auxilliary scope as well. I'll only use a 30mm or 40mm finderscope on my smallest of refractors. Funny to see a 40mm finder on a 48mm f/20 refractor, lol! Dave Bennett turned me on to the old Apogee "Mars-eye" red-dot sight over a decade ago. It is switchable between red and green dots. Too cool, wish I had another. Out of production, AFAIK. I also use the Rigel Systems Quickfinder. I prefer it to the Telrad, which, even though it works well, is just way too huge on smaller scopes. I bought the pulsing accessory for it some years ago and it is a worthwhile addition. A pulsing reticle allows fainter stars to be seen through the optical window. YMMV. Stay in this hobby long enough, and you end up with one of everything. More stuff for the kid to sell on eBay when I'm gone. What optical finders do you use regularly? (Let's ignore GoTo for this discussion.)
