I recommend the Labjack model U12 USB DAQ unit. 
http://www.labjack.com/labjack_u12.php?prodId=27.  It has eight 12-bit 
analog inputs with a +/- 10V range.   The programming interface is through 
an open API (provided, with good documentation and support).  Languages 
supported include Visual Basic, Power Basic, Visual C++, Delphi, Perl, Java, 
etc.  A good number of programming examples are provided on the Labjack web 
site.  An active forum is available as well.  $129 USD plus S&H.

Lots of digital I/O as well, if you need it for other functions.
