More CV Expander?

I think I just need to bite the bullet & invest in an oscilloscope! 

For me it is my most important debugging tool. I us both a Mordax DATA and a vpme.de Zeroscope. The former has the bigger and better screen while the later has a better time resolution.

Just chiming in quickly to reiterate that a scope, in or out of the rack, is such an absolute win. Time saved, pain avoided, more things learned, etc. Definitely worth making space for one.
