$295 4-ch 50mHz -OR- $220 2-ch 200mHz Digital Oscilloscope
jonpaul:
We found over decades CRT scopes can have advantages in some situations especially EMI, analog, audio.
We have no bias and use both digital and analog CRT as needed.
99% of the time simple design, debug, repai is fine with a 2 ch analog 10-20 MHz.
Analog scopes can last decades unlike the cheap digitals.
Some of our TEK are veterans from 19070s..1990s.
Our Yokogawa digitals are circa 1990s..2000s.
Enjoy,
Jon

@MrCreosote
Tautech is right. You should pay attention to that:

psi was just taking the piss, he well knows MHz as by now he should've improved his scope to 500 of them.

The problem is too serious to make fun of. :-DD

But why?
Isn't it more of a fashion thing?
As I said, there is this “more-is-better” logic and many here seem to be in sales and for them more ($) is better anyway. ;)
Isn't it just like four-wheel drive in cars?
Sounds kind of good, but most people living in moderate zones in cities don't really get anything out of it.
I think for 70% of scope work one channel is enough, for 99% of the work two channels are enough and for the rest there are solutions with DSOs (reference waveforms, saved waveforms..).
If I really need to “observe” 4 channels at the same time, I can add my handheld scope.
I don't doubt that 4 channels can be more convenient and sometimes even necessary, but isn't the importance for the hobbyist a bit exaggerated these days?
I'm talking about when you have to divide up a budget sensibly.

It is more like having a car with 2 or 4 seats...
If you are only doing quick poking around the circuits (service scenario) to verify there is signal and that it roughly looks the part, all you need is 1 ch.
If you are trying to look into some detail, be it analog or digital, then you need as many channels as you can.
With modern slow serial buses having up to 4 signals, 4 analog channels go a long way..
2ch is a weird in between combination, I either need only 1 or more than 2.
Today hobby users work a lot with Arduinos and microcontrollers and looking at SPI buses is common.

I agree, I find that the analog scopes are easier to use at lower freq. Perhaps the OP would be interested in scopes that are easy to use at audio freq. I really do not know which new scopes are best for his applications, I only have an Agilent 54820 digital and two analogs.
