Which do you think is better cost wise and just in general: Normal diesel fuel, Home brewed biodiesel from the biodiesel home brew kit (http://www.biodieselsolutions.com/home/home.asp), or the onboard vegtable oil kit broght out in this past power diesel mag. http://dieselpowermag.com/tech/general/0601dp_veggie/

 

In my opinion the only reason to go with the on board WVO system is if if you don't have room at home for a land based processor.
Skip the expensive BD setup you linked to and build your own following these instructions http://www.biodieselcommunity.org/appleseedprocessor/
