Featuring 72V bias technology for... er... ummm... better something or other?

Those prices are even dumber than I thought possible.  $50k for a pair of 12-foot, 10 gauge speaker wires with connectors.   For $15 you can make your own, even if you stick with such oversized wire.

Yes, it’s easy to do that, but entirely unnecessary. You don’t use it by drenching the board and rinsing over and over, you use small amounts through wipes. Think of the way you clean windows with Windex. Sponge bath, not shower.

I used to clean boards with lots of liquid, but I realized that careful scrubbing with the wipe actually works better (less chance of redepositing flux elsewhere on the board), and uses far less solvent.

There is obviously a grey area here, where the manufacturer needs to recoup some engineering cost, but sometimes it's just expensive because it can be.  (or sold to the government, as noted below)

How about the $400 USB-to-RS485/RS422 adapter cables from National Instruments? (Things that are available from name brands for $30-100, $130ish for galvanically isolated ones.)

How about when it compounds... "mil-spec" crimp pin crimper!

--- End quote ---
Honestly, $500-1000 for a mil-spec crimper doesn’t seem all that unreasonable to me, especially in comparison to $2 to $60 contacts (for things which cost maybe 40¢ for non-mil-spec).

Yes!  GPIB adapters!  Stupid expensive for what they are.
