We do a lot of high speed triggering in my electronics lab, and i can tell you that most low grade digital scopes cannot trigger fast enough. The $25,000 digital scope works, as do all of our old analog scopes.

Google indicates quite a few new analog oscilloscopes are available. My search term was just 'analog oscilloscope.' New and used ones are available.

The claim isn't that analogue oscilloscopes are generally superior. The claim is that they have responsive user interfaces, which digital equipment often does not, or at least didn't use to.

It's not even that it is, or was, impossible to make digital equipment with responsive interfaces. It's rather that the easiest way to do it often involves a delay.
