I was looking for an infrared thermometer the other day, and came across this:

It's an infrared camera that hooks up to your smartphone, then it displays an infrared image on your smartphone, and reads temps up to 662°F. Figured it could be useful for looking at engine temps, and I bought mine for < $30. Once it's here (if anyones interested) I will give it a go and let you know the results.
Video on how it works here:
