The I-zombie units are the the best. I own all three. There is no comparison between the kit you posted the links to and the I-zombie unit. The I-zombie units are not cheep but you get what you pay for. There guarantee is also the best in the industry. And their oops policy states No matter what happens to your unit, burned up in a fire run over by a truck. "We will repair or, at our option, replace any inoperative electronic product manufactured by us regardless of the cause or extent of damage for a fixed charge equal to half (50 percent) of the product’s regular retail price on the day we receive the product for repair. " There used to be fotos of the circuit board on line but I can't seem to find them right now. Anyway check them out at http://www.i-zombie.com/index.php
