Both respected dealers, pick the one closest to you.

thanks, both seem reliable as stores
Sure, usually one will only need one channel, or one channel and an external trigger input, or two channels with ext trigger. So a scope with separate vertical controls will have some front panel space, knobs, and buttons that aren't used very often. But think of it this way: You have extra probes!
(Another minus for the Rigol DS1054z is that it does not have an external trigger input. If you need external triggering, it becomes a three channel scope with the 4th used for trigger.)
sure, but I think 2 channels is the best choice for a beginner like me (who doesn't work with projects that need 4 channels)
I see that you're talking about external trigger; if I look at the specifications for example of the siglent 1202, I read:
Trigger Type: Edge, Slope, Pulse Width, Window, Runt, Interval, Dropout, Pattern, Video 
maybe I'm falling from the moon, but then with trigger can you apply a signal to the circuit? (which would make a signal generator useless ...)
Check the vendor's return policy. If there is anything wrong with your scope when it arrives, it is far better to be able to return to the vendor for quick replacement, than to deal with the factory long-term warranty service.
I also recommend "burning in" your new purchase. That is, leave it turned on long enough to reveal any faults, and put it through all its paces, early in your ownership period. You don't want to let the scope sit there unused while the vendor's return warranty (30 days maybe?) runs out, then find out the scope has a fault later on.
I will definitely look, even if for online purchases the return is guaranteed by law (I asked here for these stores, because I see that many buy from them, maybe they gave me reassurance).
Batronix seems to have twice the time to return in comparison to batterfly...
I will try to use all the functions and understand if it has problems, but for this I will need your help here on this topic: I am totally inexperienced with oscilloscopes!
curiosity:
I'd like to know if it is possible to check with the oscilloscope if a microcomputer works well?
For example in my audio amplifier I have this SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER:
If you are familiar with the chip you can check whether pins are acting weird.
Is there a clock signal? A stuck reset pin? Is there bus activity?
Provided the activity seems to be reasonable, does the clock signal look reasonable? (Although for modern processors you would need a higher bandwidth scope and proper active probes to check for signal integrity).
thanks, well anyway I see that something can be done anyway: certainly new microprocessors will have higher bandwidth, this seems to me about 20mhz therefore controllable. Of course, I guess it's not a walk to touch only one pin...
Right now it would be the Siglent. After a serious mistake they made with quality control and warranty service they have evolved and now they look like a proper, adult company rather than an obscure soviet directorate.
ok, thanks for your opinion
cheap digital scopes are small and work but are prone to noise especially if used with switch mode stuff i like my old analogue tektronics 475 ok its old but the triggering is so much better and can handle the difficult waveforms and copes with almost everything i want it to do my digital scope stays in the box most of the time the only draw back with old is be prepared to fix it once in awhile the good news is it is fixable unlike the digital ones get a cheap s/h analogue and good probes and it wont cost a fortune if you do decide digital go for the best you can afford my digital suffers from terrible noise when working on switch mode power supplies.
ste, your speech is reasonable; I believe, however, that for a beginner it is perhaps better to have an entry level digital oscilloscope and in any case I would not be able to repair even an analog one
