Gosh, I feel spoiled. We have an HP 54645D here at work, and I only have to
share it with 1 other guy. It's the "bee's knees" alright. You can do 2
channels of analog simultaneously with 16 logic analyzer channels. You can
name your signals and save the entire setup. It will trigger on damn near
any combination of logic inputs. Selectable logic voltage levels. It has a
glitch trigger mode that catches blips down to 8 ns. We have the
parallel/serial interface, too, and the BenchLink software for PC download
& analysis.  A setup like this will run you $6000 easily. Eat your hearts
out. ;-)

In answer to the original poster regarding "student" scope. Go to hamfests
and surplus places! You can get a used Tek 465 or HP 1742 (100MHz) in good
shape for less than $500. If you want cheap, you can usually find
run-of-the-mill 20-60MHz imports like Hitachi, Daewoo, etc. for a hundred
or two. In applications involving microcontrollers, a non-storage scope can
usually suffice--you write code to generate the trigger condition rapidly,
which gives you a nice bright readout on your good ol' analog scope.
