Well let's see here....

Here's the link to the EVO 2 kit. I bought the "Battery Bracket Only" for $5.99 and made my own cables as they didn't have the $14.99 option when I purchased. However, there are two positive cables stock, one 6gauge stranded and another that's made up of two 14g wires. So I'm not sure what the $14.99 gets you. The 3 feet of 6g and battery terminal-ish ends were sub-$20 at Home Depot and I had some 14g laying around so extending the cables is pretty cheap and easy to do. Oh, for the negative, no extension is necessary as once you loosen the terminating ground to the frame, it'll rotate around and reach to the new location.

I went with the higher capacity Full Spectrum P3 for a battery upgrade. I've wired in a Voyager nav unit and four usb ports to power/charge various devices, so I figured I'd go with the extra juice of the 360.

Here's a couple more pics of it all installed:
