By owners. Especially when they also own Macs.

Seriously, I've spent some observing time with Questars. Their
mechanical precision is quite impressive, and in my opinion, is what
should be kept in mind when deciding whether to buy a Questar or an
ETX. Optically, their performance is too close to warrant the extra
price. The optical difference between the two is much smaller than,
say, the corresponding difference between an AP Traveler and a
run-of-the-mill 4-inch f/8 achro.

My opinion, of course.
