Same, I have a 34401 not calibrated in probably 15 years, checked it with a new DMM6500 and they only differ a bit in the last digit

It's almost as if they were designed for that... :popcorn:

Yeah thats a great price, they never go that low on ebay. I think when I got my SDM3065X, all the similar used 34xxx and Keithley's were about the same price, and more. I have no regets the 3065x is great for me, but someday I'd like to see the difference, the top brands make.

You would not want to compare a modern meter UI and display against a vintage meter like a 34401A, when you do your comparison, you should do it against a 34461A. It is not fair to compare a 30+ year old design to a modern equipment.
While I love the quiet operation of the 34401A, quick boot time, and stability, it is no match with modern meters without logging its output to the PC. So if you are looking at capturing and displaying more than a single point of of measurement, or trying to see trends, or trying to get dual displays such as voltage and frequency, your life would be so much easier with a modern meter.
