I held off buying an IR Temperature gun because i could not find one that would read within ten degrees of true.

Last year when it was on sale I tried this one:

I like it because it comes with a high temperature Type K thermocouple touch probe too, and you can adjust the "Emissivity" of the IR spot so that it will read correctly by touching an easy to get at spot with the probe, then adjust the Emissivity setting so that the IR spot reading matches the probe.

Best of both methods.
