I would like to find a source for an AD to replace the DATAQ
DI 151RS that is not made any longer!  At $99 this AD was
a reasonable deal.  At $150 their new AD is not.

Specifications needed:

sample rate:  1 to 240 Hz
AD sensitivity:  12 bit, +/- 10 Volt maximum
output: connect to serial port of PC
power: from PC serial port
price: $99 maximum ($50 preferred!)

It seems that this should be possible with relatively few
components, as AD's are getting ever more integrated.

If nothing is available commercially, then a
design for such an AD would be second choice.
