Oscilloscope question

[eatmorepies]

Hello

I intend to buy a new cheap CRO for low frequency work (<50kHz). It's first
job will be to help me make a circuit that detects when the contact breakers
open in a magneto - testing when a low resistance coil is shorted/not
shorted. I'm not in the market for a high end instrument - in the past I've
done all I want with a 20MHz CRT scope.

Does anyone have a suggestion as to what make is reliable?

John

never had any problems with either Tektronix or Gould scopes, even the
second hand ones. Although you may like to look at the USB scopes of
PicoData and Data Translation as well (plugs into your PC).
Jack Ganssle has also published a review of these USB devices at
