Joe: Do you REALLY need a current probe? Can't you do this with a resistive shunt and an oscilloscope, using either differential inputs or simply floating the scope? That said, some of the widest bandwidth current probes (like 3 dB down at 5 Hz, very flat response, 1% accuracy) are available from Pearson Electronics: http://www.pearsonelectronics.com/ . Unfortunately, I don't know of a 100 Amp DC current sensor; all the Tek or HP probes (Hall effect or magnetoresistive) that I've seen are limited to about 6 Amps or so.
