Do you really need a newer scope?

I recently picked up a good old HP 141B (storage scope) with a 4-trace
(1404A) module and of course a 1421A timebase and delay generator at a
fleamarket for $100[CAD].  I think it was a good deal, especially given
that it still seems to work very well.  I do need to find a 1402A
dual-trace module for it since working with the 4-trace is painful
unless you really do have two or more signals to compare.

This unit will effectively replace my old tube-type Tek scopes which
were mostly dead or dying (an old 561A that's got no HV any more, and an
old 564 and 310A that both have very cranky HV, with various modules for
the 560 series including a pair of 4-trace amps)

I wouldn't mind having a >200MHz scope, and colour digital storage scope
would be a real dream, eg. a TDS5104/XL, but I don't really need either!  ;-)

What I really need now is a good low-end used function generator,
preferably with a built-in counter.
