I bought an infrared thermometer last night at Autozone for those of you who still need to pick up an item like this. I paid 19.99 for it and it works awesome!! The name brand is OEM and it comes with a 90 day warranty! What a deal compared to some of the sites I have sen them on. The cheapes I found on a site was 24.99 but had to be shipped to so I saved myself some money. By the way it is 8:1 ratio for distance:spot whatever that is. LOL I just seen some on a site that are 12:1 so I figured I would mention that. I hope this helps someone!
