  1. Just when I got used to the Agilent name, it turns into Keysight!

  2. Those power supplies are over priced on Ebay.com

  3. Hi Dave,

    Any chance you’ll let us know where to buy these auction scores on Ebay? I suspect you’d rather post anonymously and get the best price, but still hope you might send your loyal viewers a link!

    Thanks,

    Mike G
