For analyzing servo systems, especially, or any transient phenomena, a
digital storage scope is infinitely more useful at capturing one shot events
and holding them on the screen for your study.

I have a Link DSO-2102M, which is a little pod that attaches to the
parallel port of a PC. I got it for $695, I think. They have a cheaper
model for $595, I think. It has been VERY useful for servo setup, and
a number of other things that were one-shot type events.
