Hi AC_Hacker,
I searched ebay for co2 sensor too, but the cheapest sensor what I found is about $40 which I considered to be too expensive.
I bouth a katalyt (petrol) stove, what I can use to heat my small tent, or in minibus. But this stove produces co2 and water vapor. So I was thinking about what if there a lot of co2 and I start to sleep, and never finish.
So maybe a good co2 sensor with an arduino and a beeper can help me.

That company has exhaused their supply. The sensor assembly was called the 'Sensair' as I recall, and it was for sensing the CO2 in buildings so as to control the admission of fresh air.
I had seen them at around $75 to $ 224 US, which I considered to be too expensive. So I jumped at the chance to buy some for $10.
I just now did a search on ebay for "CO2 Sensor", and I saw quite a few different sensors at a pretty reasonable price.
What kind of project are you interested in doing?
