I would suggest just about any used Tektronix TDS 200mhz or higher 4
channel scope with a good display- from the mid 90s or newer.
Make sure to look up the model year to ensure it has reliable caps.
I have not been a fan of the new designed-in-china test equipment like the
'rigol'

The RICM just received $1,000 to buy a new
oscilloscope. I would like a
four channel. and color would also be nice. The bandwidth doesn't need to
be high because we usually work on ancient equipment.
What would you suggest?
Really NEW, or just new for your museum? I got a Tek 2465
on eBay that I am quite happy with, for quite a bit less
money. There are some decent import digital scopes (such as
Rigol) that many people seem to find good.
If you are not familiar with digital scopes, there are some
gotchas there. You can't tell the trigger rate from looking
at the screen, but then they can see what happened BEFORE
the trigger event, and can freeze a single-shot event for
you to look at. The good Tek DPO scopes have not come down
enough to meet your price range (yet).
