Conrad Electronic have listed the "Killer", but only for commercial customers, not for privates.
Also the HDO4000....Mysterious thing.
Nevertheless, the prices for the HDO 1000 there, incl. VAT:
HDO1072 831.81€
HDO1102 1188.81€
HDO1202 1664.81€
HDO1074 1188.81€
HDO1104 1664.81€
HDO1204 2021.81€
2-Ch models I think no one wants to have in this days(you can´t grade them up to 4), so only 4-ch are interesting.
The nearest scope model to compare would be one of their own, the MSO5000.
Actually you can get the 5074 with optionbundle included for only 950€ incl. VAT (Batronix).
If you don´t need low noise measurement capability you would take this one instead.
Pros of the new hdo are 12 bit of course and the (here proofed) very low noise, maybe additional the 1" bigger display.
But the rest goes to the MSO5074 including MSO functionality, max samplerate, max memory, max bandwith, internal 2-ch awg, bode plot and so on.
For me the case would be clear, I would take the hdo regardless of it´s limitations.
Having true 12 bits is sexier than 8.
