Need oscilloscope suggestions from a reputable brand

...He's an old-school controls engineer who worked at IBM and Boeing way back in the day before getting into academia decades ago, so I doubt he's kept up with developments in the test equipment scene...

It's almost as if he doesn't spend several hours a day lurking on EEVblog forums!  And he calls himself an addict, err.... engineer?!   pfffft.

The Bode plot functions on these scopes are mostly just educational additions, not serious R&D tools, so arguing over the finer details is kinda, meh.

I beg to differ. Recently I wanted to know the frequency response of a simple circuit and the bode plot on the scope I have here worked just fine for that purpose.

Of course, you needed a simple bode plot and it did it, that's it's job. That's why I said "mostly"
What I mean is the feature is not exactly going to have the commercial bode plot tools quaking in their boots.

Maybe, maybe not but -for example- digital inputs on oscilloscopes are likely to have put a big dent in logic analyser sales. I'd expect the bode plotting on oscilloscopes to get impedance & equivalent RL/RC circuit cursor readouts as well. That would eat away a lot of territory which is currently occupied by network analysers.

SDS1104X-E
Sweep source SAG1021 optional AWG module
Connection HW; BNC cable and Tee, 2x BNC to croc clip leads (DUT IN, DUT OUT)

Sweep = 100 Hz - 100 KHz, 4V p-p, Low res

The phase response doesn't look very smooth. Is that the best it can do ?

I'd recommend a RTB2004. With the current promotion and their steep educational discounts (~30%) it's right in your price range, an excellent scope and very cheap.

At low signal levels there is too much noise to measure the phase accurately. You'll see the same effect on a network analyser.

In my region "very cheap" has other meanings.

I agree.. 3200€ is not very cheap, even in wealthiest countries of EU.

3200EUR with the 30% education discount (assuming it applies, but with a larger purchase I'm sure it will) is 2.2k for a fully optioned 300MHz scope. That's extremely cheap.

30% on top of a 42% promotion??? 

Where do you get that idea?

It is a very good price. Not cheap. Word cheap means very low priced as in you can easily buy it with pocket money. 200-300€ might be called cheap when a scope is in question.
And even that is a stretch for some people..  But now I'm nitpicking. Sorry.

30% was the educational discount I got when I bought both promotioned and non-promotioned R&S items (and when I was quoted Keysight stuff from the same distributor), so it's reasonable to assume they'll also apply it here.

I guess we can argue semantics, but let's just call it a very good deal (and within the OP's price range) and leave it at that.
