There are several TIFF 8800 gas detectors on EBAY right now that have been going for very reasonable - okay cheap prices. Under $100 for almost new seems to be the going rate. Since I just bought one I will tell everyone now that they can’t outbid me.

Dave,
I actually put a bid in on the one that ended up selling for $256. That is a little too salty for me. I think that I would rather spend another $150 for a new one. The most I was willing to part with was $200 maybe a little more. I know the general rule of thumb is 1/2 to 2/3 of the purchase price. Unfortunately, most of the time they can't even tell you how old the unit is, let alone when it was last calibrated, or even if it ever was.
Is what I did find was a CEM model 180 (I think) supposed to be brand new in the factory sealed carton starting at $99. It states this model is the equivelant of the Fluke CO 220. I ended up buying two of them for the price of one. This guy must have quite a few, he just put another one on the market yesterday. I never heard of CEM but what the heck, two for the price of one. I will probably break the DA** thing before it ever needs calibrated anyway! That is why I bought two of them. 
Kurt,
For the tif you type in gas detector. For the co you type in carbon monoxide. It really depends on what you are looking for. If you know specifically what you are looking for, say the monoxor, you can type that in and it will bring most of them up. Depends on how they have them listed. You could also try typing in Bacharach but that will bring everything up that Bacharach makes.

Kurt, like Joe said I just typed in Gas Detector & Gas Sniffer and found the TIFs. The CO Detector sometimes came up on that one also. The one I bought on there Monoxer II for $180 I just typed in Carbon Monoxide Detector because I was looking specifically for that. I have also just typed in Home Inspector and they have come up before.

Hey Guys,
In the past I have heard of inspectors using a Tif 8800 to detect carbon monoxide. I used one of these when I was a HVAC contractor as a combustible gas detector.
I am of the opinion that this instrument is not a suitable CO detector.
Kindly enlighten me.

Hi Mike, I have to agree with you I do not belive that it is usable for CO either and i don’t belive that TIF advertise it as such, you are much better of with a single gas detector for CO either with a digital read out or a programmed alarm

To the best of my limited knowledge, the TIFF does not detect Carbon Monoxide. I would rather use the Monoxer because it gives me a numerical reading where the TIFF does not, the one I have is audible only.

Mike,
I believe you mean a TIF 8500 not a TIF 8800. The 8500 is the co detector and the 8800 is the gas detector. Sorry but you probably misunderstood what model they were using for the co detector.
