kill a watt?

[Mark Hahn]

the name is aweful, I know, but has anyone tried:

http://www.p3international.com/products/special/P4400/P4400-CE.html

it liiks like a nice (cheap) way to take the guesswork out of 
how much power a cluster node is drawing.  admittedly, it would 
be nicer if it had a serial/net/usb port, but...

given that it apparently measures V, f and PF, does that mean it'll
be hip to the true-rms thing?

thanks, mark hahn.
