Yeah, Lei Zhang has one.  I plan to get one soon.

You can also learn a lot by flipping open all the circuit
breakers in the house, then turning them on one by
one and noting the energy usage.  Only works if
you can get fine readings from your meter
(I did it here, http://kegel.com/solar.html )
and if you're the only one home :-)
