IOF, be aware of not only the temperature range but also the ratio. Check oros35's link. 12:1 vs 10:1 is better. Distance in inches : Measured Diameter in inches per. A 10:1 at 10" will report an average reading on a 1" circle. Not too bad as far as a reasonably priced unit goes. Also, look for NIST certification. Sometimes you'll find both a narrow ratio and NIST cert. for a good price.
Edit - got this backwards in my post and have corrected it based on the following - been a while I copied this quote from oros35's link
With a 12:1 distance to target ratio, the thermometer measures smaller surface areas at greater distances.
I got this one for ~$55 w/shipping a few years ago.
