With my very positive experience using the BioPro for the Dirty Hands Coop, I was invited to become a dealer for these machines. The BioPro's are all stainless steel, and I love the small footprint, the ease of use, and the fact that it has a pump to pump the finished fuel into your car or storage, right out of the same compartment that you dumped oil into 48 hours before. See my quality page for test results showing that the machine makes great fuel!
See my BioPro pages and let me know if you'd like to order one for yourself or a burgeoning coop.
