Yep, a current probe from tek for example, 100 bucks.
A scope up to 300 bucks.
Maybe in the 40 euro you´ve mentioned tax is included - I´ve payed a few less than 199 all incl.

A few years ago I bought the Siglent board.
I played around with it for a few hours, then it was on the shelf, so far so true.
But if I just want to compare something between two scopes, this is faster to hand with the selectable signals.
But yes, it only makes sense if you do that more often, no question.

They can be useful for setting up complex triggers and the like, making sure your scope will do what you want before you use it on your circuit.
And for educational situtations. This is why modern scopes use their AWG to produce "training signals".
But of course they are mostly used for demos and of course for scope comparison for reviewers like myself. Or even if you are evaluating a new high end scope and you want to easily test the functionality.

That's why I like the idea of it. I want to learn about more complex triggering, and I like the hands-on approach. Sometimes I need to test something, and a friend of mine has to tell me how to setup the trigger. I'd like to be better at figuring that out on my own.

It is a combination between a demoboard and it´s manual.
This one from batronix is good for (self-)education, here an example (translated with deepl):


--- Quote ---2.4.3 Pulse width trigger (pulse width trigger)
The Pulse-Width-Trigger triggers on positive or negative pulses, which are shorter or
longer than an adjustable time. This can be used, for example, to trigger on periodic or
repeating patterns.
Depending on the manufacturer, this trigger is also called just Pulse or Width trigger.
Please perform the following steps:
- Set Select 1 to "7" and Select 2 to "B" (burst with 12 pulses).
- Measure the "DAC-FLT" signal (J5) with a probe or connect it with a BNC cable to an oscilloscope.
BNC cable to an oscilloscope channel.
- Set the vertical scaling to 500 mV/div and the horizontal scaling to
500 μs/div
- If you trigger with the "Edge" trigger on this signal, different pulses will
trigger and you will see a changing non-stationary display.
- Now use the "Pulse Width" trigger and trigger on the pause between the pulses.
the pulses. Set the trigger level a little bit below the "pause voltage",
e.g. to 0.8 V and the polarity of the trigger to positive. The pause time is approx.
800 μs, therefore set the trigger to e.g. > 400 μs.

The 20% intro discount (good though October) works out to free shipping to the USA.  I agree that 200 EUR (shipped) is still a bit much, but I'm pretty sure I'll be pulling the trigger by the time the intro deal is expired.  I expect to benefit not only from educational aspects, but also for the benefit Dave mentioned, "setting up complex triggers and the like, making sure your scope will do what you want before you use it on your circuit".
