Well, they certainly do fail, my 34461A (2018 light colour) is currently whitescreen mode, fail to boot. Also, a quick search of the forum showed up these failures:

These are just the failures mentioned on this forum. I don't see any other modern dmm with such high failure rate here.

Of course, if you're not a company Keysight will say you have no warranty, even though you can buy from Farnell and no one will mention that. Perhaps in that case Farnell would offer one year warranty, I don't know. I hope the dark colour units are going to prove more reliable. My advice to private individual purchasers would be only buy dark units, avoid older models on eBay.

OTOH I have a Keithley 2000 I purchased non-working from eBay. £15 for some new op-amps and JFETs fixed it. I can source most parts in that meter, including the eprom firmware and am very confident I could fix it if anything happened to it in the next 20 years. Keysight 3446x/70, hmm, not so much.

Seems that Farnell UK have a new promotion on 34461A at £978 + VAT, cheaper than the 60A.

My quote for a new front panel CCA for my whitescreen 61A will likely be near half that new price. Hmm.

You can order a new front panel PCA for your 34461A from Keysight here: https://www.keysight.com/us/en/ecom/parts/part-detail.html/34460-66522
and your 34465A here: https://www.keysight.com/us/en/ecom/parts/part-detail.html/34465-66522
But they only have a few left.  I've had good luck with them but the price has doubled over the last couple of years as part inventories dwindle.
