Good that you re-iterated the truism that (unless a telescope's optics are

Yes, indeed.

The Questar, when it first came out, was worth an exorbitant price, because at the time no other telescope existed which was both compact and which had a comparatively large aperture.

But those days are now past.

However, the expensive apochromatic refractors still have one valid market -
people who need a very compact telescope, owing to limited space, might well
have money to spend on getting the best possible telescope for which they have
room. This is why they sell well in Japan.

People who live in North American suburbs with cars in their garages will, of
course, prefer a Dob.
