A few months ago, I picked up an Agilent 3458A with the high spec reference at the liquidation auction of a local electronics contract assembly house for $2000. It was in like new condition and had been maintained under a calibration contract.
They had a second one, but it was in a large lot of around 100 items in their repair department. I bid $800 for that lot, but it went for quite a bit more money. A local surplus store offered to load up and store the lot (it had to all be moved out the next day) and keep what I wanted if they could have the rest.
