Is it even possible to recoup the cost of one of those "kill-a-watt" things with savings due to reduced usage of whatever's plugged into them? The cheapest I've seen is about $30 - it'd take a LONG period of time having a light or whatever shut off to save $30, even in higher cost-per-kW states like CA...

Just curious. I like the idea but suspect the pricing makes them ultimately a foolish investment - just unplug anything with a transformer / charger and shut stuff like lights off when not using. Seems to work ok for me...
