i know, i know- i paid a ridiculous amount for what i have.  i try to just focus on the end result!  and btw, your kit DOES look cooler.  most kits look cooler, haha.  like i said, impulse buy- they were at the mall, i could actually try one, loved it- done deal.  i did no research beforehand or i would have known better! 
 
can you tell me, what is a passthrough?  is that just a battery that plugs directly into a usb port?
