and if it doesn’t confuse the user at least she or he loses time when ruling out artifacts.

I’m following this thread (and read older ones) with interest.
Every now and then I’m looking at options to complement my old Kenwood analogue scope.
I’m not looking for something cheap but rather affordable (seeing that as an investment).
I remember Tim Stinchcombe bringing his TDS 210 to Cambridge, which is not a handheld but a lot more portable.

What would you prefer? Filtering?
I’m aware that working with digital equipment has some extra/other implications but my experience with such instruments isn’t that great.
