[volt-nuts] 3458A reference boards on ebay

[Orin Eman]

There is a seller letting a slow trickle of them out there... they seem to
be going for about $165.  The current batch of two is around $100, but will
probably be bid up.

I just received one that I won.  Seems to be working fine after a quick
breadboard lashup.  I'll be making an enclosure for it next.

A little expensive IMO, but given the trouble getting the precision
resistors to DIY with the LTZ1000A, probably worth it.
