One of the major differences is in the economy of scale.  You can bet there
are millions of the $30 types sold, but probably only a few thousand of the
Horiba's.  The more ya make, the cheaper they get.  Another would be the
close tolerances and individual testing / calibration required on the
analyzer sensor, whereas the garden variety production unit just has to be
close enough to meet emissions requirements.
