If you get to doing more sophisticated electronic projects, you'll wonder how you ever worked without a 'scope.
I've been looking at the combo 'scope and logic analyzer units. I really miss having a logic analyzer for some of the circuits that have lots of "moving" parts. When I was designing video boards, the logic analyzer was incredibly useful to see how my logic was working. This was long before we had microprocessors fast enough to do video processing, it was all LSI and discrete logic.
