There is a scope made in China/Korea/wherever that shows up all over the place with different brand names crunched on it - Elenco, Tenma, etc. - you can often find these for less than $200 brand new. DON'T get a Heathkit (chances are, it was wired in the dark by a drunk baboon) or blow a wad on a Tectronix. Guitar amps ain't rocket science - stay away from the pricy {censored}.

I would agree, but I've seen quite a few Tectronix go for less than a buck....
Test equipment should cost more than a distortion pedal.
