I recently just got one of these and it is pretty sweet. You can see how much power each one of your appliances uses in real time. This information is really helpful in trying to reduce your monthly power bill. I was able to get one from amazon.com for about $25. The top power consumers that I found were our computer (250w), LCD TV (250W), coffee maker (800w), hair dryer (1400w), microwave (1500w,) and iron (1500w). Some of the more power friendly items included the stereo (30w) and laptop (30w). I have not checked the Xbox yet mainly because its hard to read the wattage when you are playing gears of war 2.
