The problem with used logic analyzers is that the prices can vary
widely.  My 1663 was purchased from eBay for $47 shipped, was clearly
from a rental service, as it was complete; nothing missing.

I use an LA less than a 'scope, so the price is right for me.  Mostly,
I'm interested in looking at peripheral device timing, so it's perfect
for the occasional head-scratcher.

I remember when we got in the then-new HP 1615 logic analyzer--I was
blown away by it.  We were using a Tek lab scope plug-in which was
pretty limited.  The idea of a piece of test equipment with a keyboard
and its own display was pure genius.  Biomation, IIRC, was also big in
the business, but not nearly as polished as the HP units.

I don't know where you're located, but if you're in a region with an
Electro Rent depot, you might inquire to see if they turn their old gear
over to an auctioneer.
