For 1 Million samples per second you might be able to use one of our PCI FPGA
I/O cards. Its just a target device so 1 million 32 bit readings per second is
about the top speed but it could do the clock generation, syncronous sampling
(say 5 channels x 6 bits per word) and have a small (1 K word or so) FIFO to
allow for interrupts etc. I'm willing to donate a card (and make a simple FPGA
config) if you like.

AD's AD7822 is $3.77 in 100s so should not be
bad in low quans
This is 8 bit 2 M sample/second, available in DIP.
Thanks, I found a bunch of half-flash parts on AD's site, pretty
close, thanks. It got me started looking in the right place.
Maxim has MAX153, somewhat older MAX153, million samples/sec
8 bits, parallel out, 5V, DIP. I asked for samples...
