Really? i kind of expected them to slap 2 front ends from 2 channel version and only cut each channel in half when using both channels from one front end. and keep them at full speed when using one from each can.

No, you can be sure that there is only one ADC in the scope which is shared across all the channels. Even the better manufacturers (Siglent, Rigol) design their 8" entry level scopes like that. Those fast ADCs cost actual money!
The better scopes specifiy this clearly in their datasheets, e.g.: Sampling rate per channel 1 GSa/s for 1 channel, 500 MSa/s for 2 channels, 250 MSa/s for 3 or 4 channels. With the OWON, you can trust that the "1 GSa/s" which they give as the only spec is the maximum total sample rate the scope will give you. If they had two GSa/s ADCs, they would certainly have specified 2 GSa/s! ;)

no, eleshop is a reputable european seller, just like batronix. you will not get any import fee if you buy from poland from them.
kokodin:
Well reputable store or not, shipping cost and potential service are still international. bartronix calculated lowest shipping cost for that rigol at 26 euro or more depending on the option. Eleshop price is listed excluding vat. My local shipping is 2 euro or free, also from reputable stores only located here. And they have 20% sale on all hantek now so the 100mhz model with function gen ends up around 200 euro deliered.(195 if i walk there 40 minutes to pick it up) no function gen 190, 2 chanel owon-rebrand 160-170 (online), 4 chanel rebrand 240 like non discounted hantek (also online).
it kind of doesn't look so good for owon anymore thanks to "black friday weeks"

As I said: I would go for the Rigol at the Batronix price.
But just one tip: If you take the Hantek, then buy the cheapest one!
So the DSO2C10. The hardware is exactly the same and the “upgrade” is a joke. (Read here: 2D15 conversion: Sets your model as 2D15)
kokodin:
"Buy th cheapest one"
ok
I went to the store and picked up DSO2D10 from store exposition because they gave me better price than DSO2C10 that was already discounted. i was only asked to keep the price a secret. but the deal was good. Scope is still treated as brand new under store 2 year guarantee, just stood in the glass box for few months and oryginal probe was missing so i got 200mhz uni-t one "upgrade" for free.
On the owon rebrand topic, i was diging around some more in specs of the 1000 series, i was wrong about record length it is 10k and 20 k not 40k so even less. But there is one oryginal 2 channel owon that is set to be 200mhz bandwidth. but it is still 1gs/s and still only 10k samples buffer. i wonder how a triangular wave would look on it at those conditions, and if it's firmware could hack lower spec models because they limit the number of samples in scopes with bandwidth lower than 50mhz quite drastically.
