Re: Low-End DAQ Board Recommendation

I concure with a previous person that replied to you.. basically get the
cheapest boards you can.  Then get more than 1 of them to meet your
channel requirements.  Since the required sampling rates for this
application are so low, really price is the only issue since any board out
there will be able to handle this application just fine.

What I would do is look at all the major manufacturers listed in the
hardware list and go to each of their websites, and see which one offers
the cheapest boards.  :)  Unfortunately this doesn't help you too much
since you still have to do all the work yourself.

I personally have a cheap Measurement computing PCI DAS-16 and am quite
happy with it as far as being pretty inexpensive and still pretty
reliable.  You can probably get even cheaper than that.. I hope.  :)
