Let's start with a short introduction. My name is Wim and I'm an electronics engineer by trade. I however ended up in the PC world as a programmer, tester, support engineer and so on. As a result my electronics skills are extremely rusty (last embedded hardware design and programming 20 years ago). Funds are limited as I have been laid off recently (no worries, please) so I have to be careful.

I've picked up Arduino as a hobby a few years back to get back into electronics.

As many, I'm in the market for my first oscilloscope. It's to accompany one of those cheap 25MHz 8-Channel USB based logic analysers. It will be used to analyse waveforms on e.g. the I2C and SPI bus, PWM signals and so on; so BW requirements are not extreme (possibly a few MHz).

I went throuh all 26 pages of https://www.eevblog.com/forum/testgear/owon-vds1022i-quick-teardown-(versus-the-hantek-6022be)/; very impressive work by camille, gyro and indman (and laurentbr). Local price of the Owon VDS1022I is ZAR 2600. To put this in perspective, the Siglent SDS1052DL+ goes for ZAR 6300.

Just before pressing the button for the purchase, I however stumbled over a Foxwell OS100 (https://www.takealot.com/foxwell-os100-oscilloscope/PLID71978770); it's nearly 3x as expensive but with a gift voucher I can buy it for ZAR 4000; I will have to invest in some probes though. The quick specs are

Product Features:
FourChannels, MaxBandwidth: 250MHz/200MHz/100MHz/70MHz
Maximum real-time samplerate: 1GSa/s
Memorydepth: 64K/CH
Automatic setup for ease of use(AUTOSET)
Built-in FastFourierTransformfunction(FFT)
20 Automatic measurements
Automatic cursor tracking measurements
Waveform storage,record and replay dynamic waveforms
User selectable fast offset calibration
Add, Subtract and Multiply Mathematic Functions
Selectable 20MHz bandwidth limit
Waveform average

So I will get 4 channels with a higher BW, a higher sampling rate and a deeper memory compared to the Owon. It also seems to have a waveform generator. I do understand from the user manual (https://www.obdii365.com/upload/pro/foxwell-os100-four-channel-oscilloscope-user-manual.pdf) that memory (and sampling) is shared between channels but it still sounds extremely good.

So the question is now what is wisdom? Go for something with lesser specs which is well known or something that seems to be quite unknown? Any advise regarding this scope and Foxwell in general?

Note:
Buying on ebay/ali/banggood is not quite an option as import duties, VAT and the likes will probably cause extremely unpleasant surprises.
