I bought a used 1662 off eBay for cheap, and it

the work I've been doing on a PDP-11. I think the external clock is often a

Sophisticated triggering is also very useful for catching a suspected
misbehaving chip in the act.
I had considered some of the more modern USB options at the time because it
seemed they would be convenient, but in the end I opted for a used
old-school tool because it had the features I needed at less actual cost. I
have not regretted the decision -- super useful tool!
My HP 1660CS with Ethernet
has ensured I?m not even remotely interested in
one of the USB options, between having 136 channels and way higher bandwidth.
Even one of the models without Ethernet would be worthwhile since they?re
straightforward to interface with via serial or GPIB.

Hmm, I'm not sure I'd say that. I have a 1650, but the memory depth is
not enough to quickly grab issues. A Logic or Logic 16 can dump a ton
of data into the PC, where it is easy to look at.
My chinese clone is of a Logic 16, I couldn't afford a genuine one since
they're ukp500 at least. Obviously caveat emptor, but that's out of my
league as a hobbyist.
Currently looking at HP1670G's in the US since they're reasonable assuming
the shipping and import charges are as quoted. Also a fellow collector is
loaning me a zeroplus 16 channel to try so that's another avenue to explore,
and there's the DSLogic Pro too which was supposed to be open hardware/open
source but development on that one stalled in 2015 and the current lot on
e*ay seem to be clones too.
