Ok. I checked both of these out and it looks like the power strip gives amperage readout, but the other unit does not. The power strip is about $75 from Amazon.com. This is probably comparable in price to what I mentioned and a whole lot easier to use.
There's also the orignal model. It looks like the EZ, but it does show amp draw. That's actually the one I have, but linked to the EZ by mistake (I don't like the EZ, yet it costs more).
