I got along without one for a long time.

Having said that, I've got a 4 channel on-screen-readout 150 mhz
scope. And I'm very fond of it. I got a 2 channel storage scope on
my logic analyzer, just thrown in for free, so to speak. It's good
for one shot events such as looking at chip timing, as well as some of
the analog issues that you might want to see in working with
microprocessors...

since I make my own electronics, I can't comment except to say, I
don't think you need it for just that. What else you do will
determine that choice.

Very much depends on what else you do.

Probably not. Depends on what else you do. Rolling your own
electronics, if analog, has one set of requirements. If simple
digital, then another... If microprocessor based, then possibly
another... Ditto for things like CNC, Servo systems, RF, HF, video...
