How much does a bio pro cost? The last one I saw for sale used was $5000!

How much of your biodiesel that you make do you sell?

I stopped keeping formal records 10 years ago. I said to myself am I spending time to save records so that I could brag about it. The closest I get now is I reset the trip when I fill up with diesel to see how many miles per gallon of diesel purchased I get. My wife gets about 125 mpgodp. I do not know yet on my Mercedes because it has only been 600 miles. It takes atleast 2000 miles to get near 1/4 tank of diesel (when I refill).

I would love to have a bio pro processor but that I can not reationalize the price of.
