[volt-nuts] Is there a "standard" much better than a LTZ1000, but much cheaper than a Josephson Junction Array?

The question about the Josephson Junction Array got me thinking. I wonder
if there are any sort of technologies that can produce a voltage with much
better stability than the LTZ1000, but without the cost of a Josephson
Junction Array. A sort of half-way house.

BTW, I see some rather battered up LTZ1000A's on eBay,


that have dents in them. They are more expensive than buying the chip new
from the Linear Technology website.


Yet people seem to buy them. Now I know the stability of those improve with
age, but when they have dents in them, its clear they have not been exactly
cared for. Maybe I will buy some new LTZ1000As and stick them on eBay for
$100 and see how many I sell !!

It seems the real cost of an LTZ1000A standard is not the chip, but the
resistors you need.
