I've been looking for JFET current limiter diodes and have come to 
two conclusions:
	1) they're too expensive, $5 ea for a 1N5314, down only to $0.85 
	   in thousands for a J557 (not cheap for a quantity price).
	2) they're hard to find, not much bigger than 10 mA,
	   and not common enough to ever get cheaper or more available.

Are there cheaper devices? Part numbers?
I could deal with maybe $0.25 in quantity; after all, it's only a diode :^)

How can I build the equivilent to a 10 mA AC (I want to pass both halves 
of the AC waveform) current regulator, using cheap JFETs, resistors, 
and perhaps zeners?

Thanks,
