E-Maxx BL System (Sub $400)

Well, my overall plan was to throw a BL system on a stock E-Maxx and then fix parts as they break. I'm starting to think that the truck would be down more then it's up until I have all the parts. So, what am I going to need to put in a BL System into my E-Maxx? I'm looking at a budget right now of around $400, but that could always change for the better. If you could post links as to where I could purchase this stuff and from whom, that would be great.
