There is an error in the table - "SDS2004X-Plus 4ch model"   SDS2104X-Plus can't be upgraded to 350MHz. Upgrade path for SDS2104X-Plus ends with 200MHz max. If you want 350MHz/500MHz you need to buy SDS2354X-Plus for ~$2799

I don't believe this is entirely correct.

Certainly it's cheaper to purchase the 350 MHz model outright rather than follow the official BW upgrade path as can be seen by the costs for each BW upgrade when applied to a $1399 SDS2104X Plus:
https://siglentna.com/product/bandwidth-upgrade-100-to-200-mhz-4-channel-models/ $1399
https://siglentna.com/product/bandwidth-upgrade-200-to-350-mhz-4-channel-models/ $1399
https://siglentna.com/product/bandwidth-upgrade-350-to-500-mhz-4-channel-models-2/ $1399

Others have tested unofficial BW upgrades to 350 MHz and their results indicate there is zero difference in the HW compared to genuine 350 MHz models.

Hey all,

I had a question...
are DSO on aliexpress and alibaba with random chinese names worth the money?

lunacyworks:
That is a loaded question. The general answer is no under most circumstances.  There are edge cases that could justify a few of the models.  One of the main issues is that they don't live up to the claims so if you go by the stated specs you won't get what you are expecting.
