"In Europe / Germany its completely legal" I envy you but I'm in California republic.
I also agree that, when I bought something I should have rights - just like human rights - to work on it as I like.
Sb says there shall only be one model, 2CH or 4CH, no scope mfg in the earth do that. I issue PO for $500K scope, various h/w and s/w options.
As for BNC, its BW is 3GHz. I do like Keysight/Tek/Lecory uses extra probe contacts, but they also in change. As far as there is USB near by, active probe is not difficult to add.
I personally not sure shall I pickup Keysight or MSO5074. I issued an PO a few months ago for co. the probes are 4x expensive than a 2nd 1GBW scope.
At last I would say, sampling rate is more important. Lab has a 200M Tek simply garbage, DOS like GUI, a Eth card costs me $600+. My 1GBW has 5GSa much better, ETH card only $200.
