Exhaust Gas Analyzers

[Ed Mellinger <meed@mbari.org>]

Hi Folks -

This might be a bit far afield for this list, but I'm wondering if
anyone has advice or experience with the hobbyist grade exhaust gas
analyzers that one sees advertised.  I believe most of them are based on
a self-heated O2 sensor, which gives kind of a trinary rich/stoich/lean
indication... probably adequate for my purposes which are to set up
carbs on old cars and bikes.  

Would welcome any comments on brands, cost effectiveness, etc.
