Chris,

Radio Spares carries a range of suitable sensors in both anologue and digital
output forms.  The digital output version tends to be too sensitive for efi
but may work well for your application if you dont want to spend too long
building an interface.  As for OEM parts, any of the local car dealers
(Holden or Ford for example) will carry suitable analogue output units which
should work well.  They are also generally cheaper than RS parts.  Try a 
current model Ford Falcon crank trigger sensor.
