I have a >2GHz scope with a 13kS/s sample rate; it does things simply impossible with modern budget DSOs.
Im well aware of ETS monsters.
I wouldn't call that a monster. It is battery powered, weighs 8.2kg, is very portable, can be operated in driving rain, and can be submerged 1m under water
Also I think that ETS has its place, especially in budget scopes with Gaussian rolloff & sample rates dropping almost to Nyquist limit when enabling more than 1 channel.
ETS is useful for far more than that, even though ETS's key advantages have been eroded by modern ADCs.
