Difference between the 4-channel 100Mhz siglent and the 200Mhz version is 700€.
But upgrading from 100 to 200Mhz will cost 1300€
Actually the Rigol DS1054Z has a much better resell value than any siglent scope. It is almost on any hobbyist / maker bench I see on youtube, I cannot say the same about siglent. There is a level where price matters more than features, and DS1054Z is the winner at that level.You can buy it new for about €380 (net. €315) through Batronix, including shipping within Europe. You'll get nowhere near that money when selling used. €200, maybe?
@0xdeadbeefCH1..CH4 is actually a magnitude better (<10ps vs. <100ps) than that from the SDS5000X. In both cases I assume that the (older) SDS5000X is just a bit less optimistic, but still.
Not sure if you copied the proper values.
Reading the SDS5000 specs it says (on the 2020-01 sheet) in the trigger system paragraph;
<9ps RMS (typical) for ≥300MHz sine and ≥6 divisions peak to peak amplitude for vertical gain settings from 2.5mV/ div to 10V/div.
<5ps RMS (typical) for ≥500MHz sine and ≥6 divisions peak to peak amplitude for vertical gain settings from 2.5mV/ div to 10V/div.

Why hell because I can simply look both on the screen and also runtime. You just have two timebases on the screen. Dual timebase mode (zoom)
How you did your works when scopes have only 500pts or 10k or 100k memory.

But there is the thing about the 500Mhz bandwith upgrade and only for 2 channel….what does it means.

In a nutshell, four channels make interleaving impossible, so the sample rate drops to 1GSa/s. And with that, 500MHz bandwidth would be somewhat pointless for anything but perfect sines.
With only two channels, interleaving increases the sample rate to 2GSa/s which is OKish for 500MHz.
Side note: didn't notice at first, but the SDS2000X Plus also lacks the VGA output and the 10MHz in/out. No showstoppers from my point of view, but worth noting.

It is not pointless - there is no such situation, BW (also scopes what are upgraded with 500MHz option) is 350MHz in non-interleaving mode for avoid Nyq-Shan violations. It is told in datasheet.

I feel you objected to something I didn't say. The "would be" indicates a type 2 conditional which is used to refer to a situation that is unreal.
Force I didn´t need in real.
