hodgey,
My dad fabricates the CSXXXX series frame for less than a FFR that will have to be highly modified to accept the CSX body cage. The suspension uses the CSX3XXX Comp/Feinstein geometry and poly joint a-arms, not FOX based items.
However I've seen FFR MKI frames for as little as $600, if you landed one at that price range you would have the cost advantage however.
