I've decided that one of the Allegro sensors is probably the best thing 
to use. I should have figured, I have a couple sitting right here but I 
didn't think about them as I have as of now only used them for DC 
applications [though I realize they work just fine for AC or DC]

The application is an AC load analyzer/meter including PFC metering and 
energy/power calculations.
I'm planning on using an 18F1220 but I fear the ADC may not be fast 
enough to measure a signal having a bad PF [watch the current through a 
CFL sometime for fun]
I do believe the rest of the '1220 should be plenty fast considering it 
runs at 40MHz and has a hardware multiply.
I'm open to any comments/criticism.
