Truck chassis - where to get?

[Madda]

I want a chassi for this body:http://www.rigidrc.com/shop/option-p...o-700-kit.html anybody knows a good place? Or maybe I should build everything on my own? Then from where to get all the parts?

Sorry for a lot of questions but I don't know nothing about truck building, I've only done things from scratch

Oh, if somebody knows another place that sells the same body or new actros cheaper, then tell it!
