Picked up a Xantrex XHR 40-25M power supply that appears to never have been used. Looks like the only time it was ever taken out of the box was to take pictures for the auction listing; there's not a spec of dust or dirt inside or outside. Got it from a government auction for $170USD shipped.
It even came with the original manuals, including full detailed schematics, parts lists, and detailed descriptions of the function of each subcircuit. I don't know if I can legally upload any of it because the manuals explicitly state proprietary/copyright protected and are for US government use only.
40V @ 25A continuous rated, 10-turn pots, remote voltage sensing, can be controlled externally with digital logic or analog input (resistance-based or voltage-based), all the good stuff. Looks like it was manufactured circa 2000. The US government must have paid a fortune for these.
I'm mostly excited because it's the first decent variable power supply I've had, and I think I got it for a decent price as well.
