Thanks for your comments!

So the takeaway is: no
matter what, I should plan to recap the PSU. Fair enough ¡ª that¡¯s
the kind of work I¡¯m used to and can handle.
If I understand you
correctly, the 24x5 (non-A/B) models don¡¯t have NVRAM or SMD
electrolytics, which makes them a bit more maintenance-friendly?
So for someone like me,
who just wants a relatively low-maintenance scope, the 24x5 might
actually be the sweet spot?
Or to put it another
way: I was assuming that '90s-era hardware (like the B models)
would be the safer bet compared to '80s-era tech ¡ª but for my
specific use case, that might not actually be true? Anything 30 years old is likely to need some maintenance! The points I've mentioned are the common pain points, but there are, of course, others. Make sure you see evidence the scope is fully working, preferably with the screen showing the results of the inbuilt self tests. Ignore "powered up but not further tested"!?
Judge for yourself whether someone will pack it competently for shipping.
My preference is for the 24x5, but the A and B variants offer a little more bandwidth, plus some measurements. Personally I don't think either of those is necessary since I can look at the trace and do some simple mental arithmetic.
Do listen to other people's opinions, and match them to your requirements.?
There are many discussions on this mailing list, and on EEVBlog forum.
