John, for fast FFTs, it's hard to beat Array Micro's unit (if memory serves, it's called a DASP6100). I think the set will allow you to do a real 64K FFT in aroun 1 to 2 milli-seconds. If memory serves, a real 256 FFT can be calculated in _realtime_ for a 0 to 20 kHz spectrum. I don't have Array Micro's number off hand but they are in the US. Maybe someone else has their number. Or, failing that, I could find it out in a day-or-three.
