GFCI offers different protection than ground. If you touch a hot wire and then a properly grounded connection, you'll get a shock. If you do the same thing with a GFCI circuit, it will see that the path is not going through the neutral line and trip. If you didn't have GFCI, the ground connection in that fault scenario makes it MORE dangerous.

This may be a stupid question but I am not an Electrical Engineer nor do I pretend to be one. I rather rely on one of you experts. Will a Furman Conditioner (Which is what I have in my Rack http://www.furmansound.com/product.php?div=01&id=PL-PLUSC) do the same job as the GFCI (The Home Depot Link above)? I don't have a problem getting the GFCI I think $30.00 is cheap.

No, if it did it would list that as a feature and require a reset button for the GFCI. It looks like a simple voltage spike clamp.

I have a couple of simple plug in GFCI's that are the same brand as the cable Mike linked to. You simply plug them in to the edison outlet and then plug your power cables into them. They are the simplest way I have found to add GFCI to an existing circuit.

Correct.... The Furman is a spike/noise clamp unit, definitely NOT a GFCI, and it will do nothing to prevent electric shock if powered from an ungrounded outlet.
