for profit) and teaching it I hold the scope for last
save for
analog and even then I've done other things first.
I'd suggest that learing how to use more basic tools fully
and understand them completely before a scope is not
a bad thing.
I agree, the first thing I am usually looking for is continuity, then maybe
a voltage. The class of problems were a scope is really handy are the
"partially" working circuits or devices, the rest I do fine with a DMM.
OTOH I can't think of much I would attempt to prototype without a decent scope.
