www.supermediastore.com has the "Kill A Watt" power/energy meter on sale for
less than $19, shipping included. I have two, and I might buy another.
Consumer Reports says it's accurate within 2 or 3%.

Rush right out in a buying frenzy!

Is this a clip on type? If so it might be 3% accurate at maximum load, but
if it's like UK ones painfully poor at below say 3 kW.

Ah - right. Those can be fine, accuracy wise. But of very limited use.
After all it's not difficult to work out what most appliances cost to run.
The sort which gives a whole house reading are a good idea - but sadly
inaccurate due to clip on design.

Not a brilliant price either - I only paid 10 gbp for one.

When I get around to it, I'm going to put it on my fridge for a few days. I
want to see exactly how many kWh it draws over a week or so. You can't do
that with a clip-on, because refrigerators run intermittently.
