Yeah, this is definately not a home brew kit. The average cost of a biodiesel processor is $.80-$1 per gallon of annual production, this one does in the 400,000's annualy, so its an opportunity for someone with the need for that much fuel to pay about half price. An ideal candidate for this processor has a fleet of diesel trucks and spends over 10k a month in diesel fuel. Even if they only saved $1 per gallon, the return of investment is around 18 months.
