Out of curiosity, how often do you use a Kill A Watt meter? $23 seems like a high price just to plug a device into for a couple days to say "oh maybe I should turn this off more often"
Myself? Never, as I don't have one. When I want to find out what a device is consuming, I hook it up through my Fluke multimeter to obtain the current draw, then calculate the rest.
But, for general use by anyone not a EE or Electrician, hooking up a general purpose multimeter to mains power to measure current draw is a not recommended, much danger here, operation.
Therefore I erred on the side of caution and recommended the method that was most safe for all involved in all situations.
What I suspect you will find, however, is that you will find uses for the device that you never anticipated once you have one.
I've always had the same concern stopping me from getting one. I wish I could go to Best Buy or someplace and rent the darn thing for a few hours instead.
