What's a good 2 channel USB DAC?

We're looking for a module that does ONLY DAC, not any acquisition stuff. Most things I've been able to find also have a million acquisition channels built in.
Anything along those lines out there?
Thanks

    It depends whether or not you are writing software for it. This module www.measurementcomputing.com/usb-data-acquisition/miniLAB%201008%20.aspx has 8 channels.

    I did a little work with a measurement computing module and I like them because they use the hid protocol and only take one external file to operate, unlike some unnamed cheap daq modules on the market based on the ftdi chip and propietary libraries and protocols that take about 10? dlls and misc to operate. Measurement computing also has extensive .net examples to get you started.

    Part of the reason there are so many with 8 channels is because 8 take no more work than 2 except for the slightly large circuit board and box.

    A pic18 or pic24 could do this easily.
