Meh. I use a 'scope as my primary probing tool. It sits on the workbench, so I only really use a logic probe when away from the bench. I kinda like the more detailed view of what's happening... but to be honest, most cases when you find a dead output, it'd look just as dead with a logic probe.
Thing about an oscilloscope is, it's not any sort of "magic" diagnosis machine (like the Fluke 9010 sort of is). A scope is nothing but a high-speed (low accuracy) voltmeter. It draws a graph of the voltage vs time at the point you probe (or two points, if you have a dual trace scope)... that's it! It's up to you to determine what that means. As others have mentioned, a scope if essentially useless without at least basic knowledge of electronics, and better still understanding of the schematics; or at the very least, information about the specific component being probed.
If you haven't read "The Book" at Atari, do that first.
