Last year a picked up a 150 MHz mini Tektronix dual trace, digital
storage scope with manual and two probes at a garrage sale for $75! It
was a bit of a gamble because I couldn't try it out in advance, but it
turns out towork great. With the storage features comes a whole raft
of trigger modes, without the manual it would have been really tough
to figure them all out. The storage aspect makes debugging digital
stuff much easier, you can see what happened before the trigger.
