Should I buy a Rigol MSO5000?

In fact, I hadn't even 1x probes in my mind at that moment. But you are of course right, In this case, bandwidth must be renounced anyway.

How many adjacent samples does the MSO5000 average in hires mode?
The handbook obviously does not tell. I only find

    In "High Res"mode, the signal bandwidth does not exceed 1/32 of the sampling rate.

which would imply <= 250MHz bandwidth @8GSa/s (or correspondingly >= 14 moving average filter taps).

EDIT: I just saw in a different thread your statement

--- Quote ---You have to turn it on and set the number of oversamples (8x, 16x, 32x, etc).

What is the maximum value that can be set?

Here's a picture of what your sock puppet says is too complicated/fiddly/generally impossible to do:

I do not got a sock puppet and this is not what I´m asking you for, I already know this pic.
So I´m still waiting.

Taken from Rigol site.

LOL they are comparing to old SDS2000X that is not made anymore....

Certainly if a scope doesn't pick a signal because it is to small, a preamplfier will have a similar problem.

Well, there isn't a single, universal pre-amplifier suitable for all situations so you can't go from generic requirements. If your use cases vary widely, you'll need a wide variety of pre-amplifiers. An oscilloscope input is pretty allround already but don't expect something similar from a pre-amplifier that is tailored to a specific use case (like amplifying RF signals, picking up low-level signals for audio / sensors, differential input, etc).
