The hantek 4204c is a 4 channel 200 mhz oscilloscope with free decoding and it also have can decoding which the rigol does not have, and it was recently 389. It is about the same price also on ali express. The only thing it does not have is the long memory but everything else is better.
Yes, but the OP's question was about
DSO4102C, not 4204C. The latter is a bit better deal, given the 4 channels, but this entire series has only 64k memory/32k dual channel and that is only a paid option, default is 4k??? That is completely ridiculous.
The Rigol has 24M (12M standard without options). That's a huge difference, certainly more important than the 200MHz bandwidth vs 100MHz on the Rigol for a beginner. What good is having something like a CAN decoder when you have only 32k of memory to record the data in? On such a low memory scope the protocol decoding is mostly a gimmick, IMO. Now to be fair - Rigol DS1054z doesn't use the full memory for decoding neither, it decodes only what it has on the screen and you have to scroll through the captured data to see everything - which is also retarded. But at least you can actually capture the data (and then potentially decode them offline on a PC).
The same with waveform update rate - 2k/s on Hantek, 30k/s on the Rigol - good luck hunting for glitches. Don't think that the Hanteks have intensity graded display neither.
What I like on the Hantek scopes is the set of vertical controls per channel (Rigol has multiplexed controls) and that it has the 500uV/div range (Rigol doesn't or rather it doesn't work if you try to enable it). But those are really minor issues, IMO.

It also does not have the rms compensation problem that the rigol have. What good is low price if you can not measure rms correctly?
Don't worry, Hantek has plenty of bugs of its own.
And buying a scope from AliExpress is nuts, IMO. It is easily the most expensive instrument a beginner will buy, good luck trying to get a warranty repair from a Chinese seller should anything go wrong with it. So comparing AliExpress prices with regular western sellers is crazy. And even then Batronix manages to have the same price, including VAT - which one would have to pay on import on the Hantek device from AliExpress here (without VAT the Rigol is some 330 euro).
Really don't see how the Hanteks are a better deal here. DS1054z is still an amazing deal, despite the age. If you want something different and/or more recent, then the newer Siglents are major competitors in this price bracket. But Hantek? Not even close, IMO.
