So are you a beginner with scopes or only with digital storage oscilloscopes (DSO)?

Uni-T oscilloscopes are not so common here. There is little information from the field.

Normally "we" would recommend this one if it can cost more than $250:

But since you don't want to "learn a lot of new stuff", it might be a bit too complex. I don't know, I have a cheaper scope myself.

I'm very familiar with scopes and really interested in getting spectrum analysis features - the Uni-T waterfalls really caught my eye - no one has them  The waterfall would be useful tuning pianos and other transient signals like room acoustics (but I doubt these low end scopes are fast enough to capture room dynamics - maybe reverb in a church.  The waterfall is like having a microscope for the first time - you put everything you can think of under it.

I don't design circuits and have yet to do any kind of RF repair.  This is "new stuff" I refer to.  My main effort is diagnosis and repair and I have never fixed a radio.  I wouldn't rule it out, but I would definitely no invest in RF repair capability - by the time that might happen, 1 or 2 generations of improvements/cost reductions will have happened.  Never invest in tech you plan to use in the future.

"Beginner" was aimed at how to address my original question:  Looking for consensus choosing which of 2-ch/100mHz -v- 4-ch/50mHz given no other information.

But there are even better deals now from both Rigol and Siglent. The idea is to get a 4 channel, less MHz, but that is easily unlockable to more MHz.

2-channel? Nah.  :-//

As far as UNI-T, no. They have crap products, I'm convinced at this point, due to my horrible experience with UT-61E+ and BLE dongle. The dongle itself does not work the meter, and even if it worked, there is no software for the bluetooth on PC. Owon is a much better brand than UNI-T. Realize what UNI-T means, UNI-TREND. Now, realize that their entire lineup of products is not professional.

Spend a few dollars more, get a good tool from excellent brands like Rigol and Siglent. Skip UNI-T alltogether, avoid like plague.

UNLOCKING:  I totally forgot about that.  Will probably have to re-evaluate: ability to have 200mHz for a 100mHz price is nice but I doubt I need that at all.  But it does sweeten getting a 4-ch.

* (It really annoys me that they do stuff like that.  If it's a 200mHz scope for the same manufacturing cost, set the price for desired profit and quit selling the 100 detune.  But you can make more profit if you do the 100/200 dance.  NOTE:  companies that do that rub me the wrong way - it indicates they are greedy.
Uni-T:  All I know about them is a lot of people like their IR imaging guns.  In fact, looking at digital scops over the years, I never heard UniT mentioned.  They make some expensive stuff and they have insanely deep memory 56M in the 2 scops I mentioned.  Their MSO7204X 2GHz 4Ch Mixed Signal is a $16,000 scope - so they have a pro and a consumer line?

HANTEK:  This was the first cheap digital scope I became aware of years ago and without doing any research is one I would probably get if I wanted the lowest cost.  However there is a recent model that had all kinds of problems with firmware I believe that was quite the "hobby" to straighten out.  That really soured me on H.

TEKTRONIX:  I'd like to know what Chinese company manufactures Tek digital scopes and what other brands.

Get over it !  :P

All scope manufacturers have been restricting BW with SW for decades, all of them !

And BTW, if you really wanna be part of an engineering forum learn to use the correct denominator.
M = Mega    u = Micro

Psi:
I would go with 4ch over 2ch any day.
Unless you know for sure, based on what you do, that you'll have situations where you can't get by with 50mhz and need the 200mhz.

Being able to show 4 things on screen is just more useful more of the time.

@MrCreosote

Tautech is right. You should pay attention to that:

mHz = Millihertz. 200mHz means 0.2Hz, i.e. “once every five seconds”.
MHz = Megahertz.  200MHz means “200 million times per second”.

And while we're at it: Hertz is not a plural.
1Hz is also pronounced 1 hertz, not 1 hert or hurt.  ;)
