The guy that makes those inexpensive little precision voltage standards has a new design and new web site.  

His old units were based on the XICOR chip (which XICOR killed because of bad yields).  His new design uses a TI REF5050 chip.  He has 2.5V, 4.096V, and 5V 0.01% units for under $30 each.  I really like his stuff.  He will recalibrate them against an HP3458 for $5...
