there are also very active lists for 8/16 bit controllers, but the
people I wrote about also don't look/write in mailing lists.

You forgot the ";-)" didn't you? Only able to talk about 68HC12 here,
but the documentation to that part is about the worst piece of tech
write I've ever seen. If you want unclear, obfuscating, verbose and
chaotically organized docs, then go for Motorola. I don't dispute the
status quo of documentation of other, marginal microcontroller
vendors, but big big Motorola should be able to afford at least some
input from a competent tech editor when producing another 400 page
handbook for their mcu's.

I've sorta given up on Cygnal/SiLabs. They look like fun chips to
work with, and quite powerful, but every time I had Purchasing quote
one of their controllers, it came out 2x the next worst competitor.
Digikey's price for a single C8051F300 is over US$6.50, and about
US$3.60 for 1500.
And I don't need all that much power for the app I had in mind. The
PIC10 is less than US$0.50 in quantity (Digikey's price for a single
is about US$1). Anything less than a buck (with an 8-bit ADC) would
have made it worthwhile.

I have no problem getting the chips via www.digikey.com in small quantities.
I haven't tried getting samples from Freescale yet.

There are active mailing lists for the 32-bit microcontrollers - I don't
know about the small ones. We've also had lots of information from our
distributers.

For the smaller devices, the CodeWarrior tools are (as far as I know) free
or cheap for limited sizes of program code, though they are expensive for
the unlimited versions. BDM interfaces should be reasonably priced. For
larger devices (i.e., 32-bit chips), there are gnu tools, cheap BDMs, and
open-source OS'es. I can't comment much on the availability of small
quantities, however.

Think the ATtiny13 and ATtiny15 (and soon t25/t45/t85) should fit that
description nicely as well.

Silicon Labs, and Philips (coming) also have 3mm x 3mm package uC,
only theirs DO have ADC...

None with ADC unfortunately. I had a perfect app, if such existed.
One analog in, one discrete out, a tiny bit of code, and presto... Oh
well.
