Eric,

Just a word of warning when looking at A to D cards, you'll want to look 
not only at the hardware specs, but also at the software interface to it. 
I've been attempting to use an Adlink PCI-9812 card 
(http://www.adlinktech.com/PD/web/PD_detail.php?pid=33&seq=2&id=3&sid=22#) 
which has very similar specs to the MC4020 card. While I haven't given up 
yet, it has been very difficult to integrate this card into a working 
application because of the way the drivers are put together (they won't run 
in a multi-processor environment) and because of the inefficient manner in 
which data is transferred through the high level interface provided with 
the card. There is also a distinct lack of good low-level programming 
support, so the task of coding a custom driver is looking rather daunting 
at this point.

I don't know what your background is, but you may want to take these things 
into consideration before you make a purchase.

Alan
