True, 0.01% resistors are available, *but* they are extremely
expensive (over $100 each) and they are made when and if the
manufacturer sees fit to do so.

Not so.
RS Components have 0.01% resistors for AU$34.50 (US$26)
Farnell have 0.02% for as little as AU$20


You guys are paying *way* too much. We use Riedon .01% precision resistors
in our A/D products, and pay about 5 bucks apiece. Their site is down at
the moment, but even Digikey has .01% resistors for around the same price:

"Your search criteria has expired"
Furthermore a search on "34342147" (no quotes) gets zero matches.
A search on "3107" (no quotes) gets matches that are not better than 1%.
Strangely enough, a search on "precision resistors" (no quotes_ is as
bad.
Worse, a search for "resistors" and wading thru the various types
gets *at best* Chip Resistor-Thin Film(67311 items) with 0.02% as the
best or tolerance listed.
So......
Where are those mysterious 0.01% resistors???
