Scopes are like libraries:

ANY scope is better than no scope.
Any library is better than no library.

A fast scope is better than a slow scope
A two channel (or more) scope is better than a single channel scope
a DSO is better than an enalog scope, in most cases

but if you don't have any scope at all, and have no money, a really cheap
used student model from 1960 will be a great addition to your lab, and won't
set you back much more than a week's worth of  big macs.   90% of what you
use a scope for will be will under 1 mHz, single trace, repetitive waveforms
that won't require DSO.

Another guy in the lab gave his old scope to his kids, who built it into
part of their "submarine control room" consisting of blamkets over cardboard
boxes, a cheap student model scope, some relays and wires and a burned out
audio board.
