For those of you who have ever done any troubleshooting on wiring problems or tripping circuit breakers, here is a very good aid in finding problems. Radio Shack makes a Infrared Thermometer ($39.95) that is a point and press type thing. It will read the temp of whatever you point it at. Very useful in find hot spots caused by broken or almost broken wires, bad circuit breakers, etc. It's saved me a lot of time a couple of times.
