... actually I see ads for used emissions equipment in the local news-
paper from time to time ... often for much less than $750.  I wish I 
was able to tell what it was simply from the model number, but usually 
I have to call the seller to find out if it measures CO.  So far every 
time I've found one that did measure CO someone has beaten me to the 
punch ... :(  Good luck! ... very few of these things are self powered 
or portable however ...

I've been off the DIY-EFI digest for a while, but I remember talk about 
the UEGO sensor, which was a much more precise device than a standard 
OXS ... and quite a bit more expensive.  If you need to have a meter 
that you can't buy otherwise you might need to build it yourself.  Per-
haps a UEGO sensor with some interface circuitry can hook up to your 
laptop.  You might want to pose the question on the diy-efi list yourself ...

HTH!
