[volt-nuts] Analog Data logger search

[WarrenS]

Yes, a DMM that does fast data logging to a PC would work fine for those 
that already have one.
It does not make such a great universal solution for most.

Anything under a hundred US dollars is worth considering.
What I'm looking for is a 16 bit, bipolar, solution to upgrade
a small, obsolete, DataQ, RS-232, serial, product that uses the 12 bit ADC 
of a two dollar Pic micro.
