This is a good example of a de-facto standard that many people don't need.
I have a car with 5 seats, but it's almost exactly like an oscilloscope: 70% of the time one seat is enough, 99.9% of the time two seats are enough. I've never used more than three seats, as far as I can remember. But hey, "normal" cars have five seats. If I had to pay 12% more for the rear seats, I would have decided against them.

With 2 channels you can compare two (or successively n) signals (phase shift etc.), that's fundamental in my opinion.

There are logic analyzers for SPI etc., no?
MrCreosote:
Thanks for all the tips. My bad about the M vs m - I really didn't give that a thought. But I did know to capitalize H in my fence.
Again thinking of what my Real Question is: My electronics bench is 5' x 2' and I do not have room for my Tek 465B which I love dearly.
So keep the Tek if I get backed into a corner and need a real oscilloscope, but to keep space on the bench, get something throwaway cheap: Like AliExpress Hantek $172 or Hanmatek (! LOL) $125...
OR Something completely different:
Get a decent HANDHELD OSCILLOSCOPE which would also be handy portable - something even a digital oscilloscope really isn't.
This portability is something I would use.

A 7" display DSO is VERY portable and as you're limited for space as I was many years ago when I ditched CRO's and went entirely DSO.
A handheld scope is in no way a replacement for a DSO !
But this is to be a new world for you and I understand the apprehension albeit misguided.
Sale of your Tek 465B could help fund something decent.....

You would have to define your needs more precisely.
So far, I'm not quite sure what you need, even roughly.
A 7-seater car? A pickup truck? A Ferrari? ;)
The handhelds are fun and often sufficient, but as Tautech says, they don't replace a benchtop DSO.
Even the cheapest Hantek offers much more for the money, including fundamental things like sampling rate, sensitivity, trigger options etc...
But if, as you say, you value a fast, high-resolution FFT, then the cheapest scopes are not enough.
The handling of the Hantek, for example, is sometimes quite fiddly. There are people who are driven crazy by this.
I don't know what to advise you. Sometimes there are things you don't even think about. For example, fan noise or start-up times.
This can also annoy some people.
That's where handhelds or cheap scopes can have an advantage.
But as I said above, I think the Siglent SDS800X HD models currently offer the best value for little money.

Smepic:
Take a look at the Rigol DHO804. They are decent scopes (12bit, 1M FFT, hack up to 200MHz), small and "semi-portable". By "semi-portable" i mean that can be powered via USB-C power bank .
And this week they are on sale for $279.
EDIT: Correction, 279€ in Europe (30% off from 399€). USA/Canada are 374$ (15% off from 439$).
