Well.... Ohhhh kay... but here are a bunch under a hundred bucks.

These have other uses...

I use mine to check the temperature of my aquarium, the chili I was cooking yesterday, room temperature, my oven temperature.
You can use these to find which cylinder is missfiring. The one with the 20F colder header pipe....
