    Hi Charles:

    Checking ebay, it looks like there is lots of choice these days, and you can get infrared thermometers with very good specs, much cheaper than a few years ago.

    I can’t vouch for any of these, since I haven’t tried them. However I have been buying lots of small electronic items lately on ebay from China, for incredibly low prices, and have not had any disappointments so far.

    Right now I am using a Fluke that I paid about $300.00 for 5 years ago, that goes to 1100 F. and has a distance to spot ratio of 50:1.

    “Distance to spot ratio”  means that it can resolve a 1″ circle from 50″ away, or a 1′ circle from 50′ away. The cheaper thermometers have an 8:1 spot ratio, which means that you have to hold it right up to what you are reading and can’t read stuff that is high up, for instance.

    Here is a random sample from low end to high end:
