I am but, that means little.  I actually troubleshoot stuff,
in the practical world doing is the important part.  Experience 
doing is extremely useful.

My everyday bench scope is a B&K 20mhz dual trace as it's fairly 
small and warms up fast.  I have no hesitation to use it for logic
in the 20+ mhz range, however I understand how it behaves and 
what I'm seeing as a result. If I realy need to see more I have
"big guns" for for the task but rarely use them.  I do more with a
VOM and cheap logic probe before I resort to scopes and logic 
analysers.
