True analog scopes
BillyO:
My Tek 465 works perfectly. It gets used frequently as I just like dealing with quality. If I don't need a DSO's "features" or don't need bandwidth in excess of 100MHz, I use the Tek. It's from a time where quality was paramount. Tek scopes to day can't hold a candle to it's beautiful, solid build, let alone mi Siglents.

Just go on digikey (or whatever) and filter the oscilloscopes by "CRT"
TimFox:
I did that search on DigiKey, specifying "active" instead of "obsolete", and it returned only one B&K Precision 2120C 30 MHz unit, lead time 10 weeks.

That said, I still reach for my 54622A and my Tek 2235 more often than I reach for my newer, higher-performance scopes, and this is because for a good portion of what I do, the 54622A is fast enough, and it is far less likely to annoy me than anything more recent. I actually like the TDS220 series for this reason - it's pretty usable.

I have an Agilent 2000X for that. As a DSO, it is now somewhat outdated (in particular it has pretty limited memory). But it is an amazing CRT emulator. >:D It responds instantly and basically "just works" with minimal fiddling. I still have a nice analog Tektronix somewhere but I'm keeping it purely for the nostalgia (along with a couple of Hamegs). I can't think of anything that would make me actually want to use it again for real.
I have no love for the TDS220 though. Yes, in many ways it was quite revolutionary in its day (form factor, 1GS/s at low price point). But it was slow and had an awful screen without intensity grading. It was also ubiquitous (particularly in the education sector) and frankly, it gave DSOs a bad name.

Aliexpress has a few, you can even get a round-screen one for real retro effect:

There's also some scary-expensive ones:
