the kill a watt EZ has the added feature of telling you how much the appliance is costing you in$$. You have to put in your con ed kwph charge into its memory. On the older one you have to do the math yourself. They are only good for 15amps, and i bought mine for $20and $25 , costco even had the EZ in two packs. i recommend a 6 inch extension cord,since they are like a big wall wart. They are only good for 15amps, but tell you a lot about your incoming electricity and your usage, great to see how much vampire power drain cost you per year. The EZ is newer and better, it will tell you the daily,weekly. yearly cost.

It also tells you your ac cycles and voltage, Last week during the heat wave i was only getting 116 volts. I wont get on the elevator when i see that.
There is also a micro PC home brew that cost under $50, you put it on your power meter,no seals or any damage to the co ed meter. It transmits to your receiver and you can see your total energy usage. Not sure if it would work in a apartment building,unless you tapped into a unused telco house cable to the apartment.
