If you can find a meter that is inexpensive and can reliably detect elevated CO2 levels then I'd say use it, but the lighter test has proved reliable for many cavers for a long time so I wouldn't discount it.
Here's one of the previous threads(there's been many) http://forums.caves.org/viewtopic.php?f=1&t=10918&p=131808&hilit=breath#p131808
Here's a great paper on the subject Naked Flame Test for, and Human Tolerance to, Foul Air in Caves
The best advice is, “If in doubt, get out”, in an orderly manner.

and here's a paper to emphasize that co2 is a health risk that should not be underestimated.

Thanks for the paper, I'm already reading it :kewl:
What tempted me was the relatively low price and list of gases it'd detect without the added open flame risk.
