Hello,
you also need to keep one more thing in mind which is bad for these seeking a cheap 3458A.
If you take a completely beat up one, and a decent lawyer, Keysight will - AFAIK - repair it for a reasonable set fee. This essentialy gives a new multimeter and puts a very high minimal bound on sales prices. If I would find a 3458A in the bin tomorrow and it was shot up with a Gepard rifle and was urinated on by both fox and female, as long as I can find all the parts, I would try to get Yaniv to force KS to honor its repair policy and flog the result on ebay.
Something I have had a lot of fun with is SolarTron. But I am not a big voltnut, my 7061 recently failed and I dont miss it so my wife balks heavily at the cal and repair cost.

With best regards

The recent introduction of the RoHS "black" edition indicates that Keysight isn't planning to replace the design. Old designs which are still in production hold their value well. The 34401A continued in production for an unusually long time because it was stipulated in so many test equipment lists in service manuals.
I picked up a couple of 34401As via ebay for ~$250 each. One was wonky. The cause was solder flux from an old repair. I cleaned it with isopropyl and it is the best of the pair. That's about 25% of the cost of the new equivalent. There are several on ebay now which will sell in the $200-300 price range. The same valuation puts an easily repairable 3458A at $2350. And an incomplete unit whether missing or unrepairable board at ~$1000-1500 as a parts mule. Provided it's not a set of known bad boards.
A working 3458A is worth $3000-5000. With RoHS compliant models available, there should be a drop in price on older units. But not likely to be huge.
Volt nutting has become rather fashionable.
Have Fun!
