I know at least for myself, the for sale section is what keeps bringing me back to VS. I haven't found a whole pile of valuable info for performance beyond which bolt-on to choose, and nobody makes anything for the level of performance I'm shooting for. The marketplace, on the other hand, is useful to enthusiasts with all levels of goals and knowledge. Unless there's a "fabrication" subsection that I haven't found? I suppose I could post up my howto on the 240 heater core chainsaw swap. That'll freak out a few of you folks. :D
