FWIW, I have recently bought an NGK UEGO and have the prices sitting in
front of me.  Sensor AUD$950, loom $120 and controller $750 ex tax.  They're
not cheap!

I ran some calibration runs last week against an ADS9000 four gas analyser.
There is some problem with the UEGO in that the voltage output wrt AFR
has a 1.7V discrepency at stoiciometric and about 1.0V at the extremes
of my tests (12:1 and 25:1).  I'll be faxing NGK later today to find out 
why the output is out of spec.
