So I think I'm gonna buy a scope next week.
There are 2 products I had in mind.
A Rigol VS5042 USB for about 430€uros and a a Rigol DS 1052e digital Scope for about 568€uros
It should be able to make nice pictures.
I'd prefer the real scope over the USB thing 'cause its quicker used (no need to start a computer, install drivers or so, just plug it in and use it)
