I don't do high-speed digital logic or anything like that; I primarily work on antique and vintage electronics, stereo hi-fi gear, microcontrollers and ham radio transmitters and receivers.
I have an inexpensive Rigol 100MHz scope, and an HP 16500B mainframe loaded with six more 100MHz scope channels + a pair of 250MHz channels; then I have a synthesized signal generator good up to 20MHz, a Leader FM Stereo Synthesized Signal Generator, an HP precision audio oscillator, an old AM RF generator from the early '50s, a handful of multimeters, and a very nice soldering iron, de-soldering iron, and a fume extraction system.
In all honesty, this is way overkill for what I work on...but part of the fun of having a good day job and a profitable hobby is being able to buy expensive toys that make everything just that much easier and more fun to work on.
