Cheap DSP cards (PCI) and drivers

Hello,

I am looking for a cheap (PCI) DSP card (and OS X driver) for one of my OS X boxes. These things are usually made for the digital music community; I want to use it for data acquisition in a physics lab.

For the last few years I have been using an old turbo color NeXTstation for this purpose - it has a built-in DSP and I have been able to use it to control an experiment using the digital inputs/outputs from the DSP and count photons (up to 1 MHz) using the DSP. I am delighted with the performance of the NeXT (for an '040 machine) and ease of programming (in Obj. C) and want to upgrade to one of my old beige and BW OSX boxes. Unfortunately, the Macs didn't come with a DSP, so I need to add one (the NeXT also had DSP drivers in the free MusicKit). (The alternative Labview approach to DAQ is completely unacceptable to me, with its limitations on the Mac)

Thanks.
