I've been doing a ton of research on this for the last year or so too. Beware, those bio machines aren't as easy to run as Trucks made it look like. I'm not trying to discourage anyone but know ahead of time that there is a lot of chemistry involved and hands on time during the processing. There are also many differant types of machines out there, ie. appleseed processor, fuelmeister, etc. Some sound great until you do some serious research and find out guys that have tried them had nothing but problems. The appleseed seems to be pretty well like.
If you've got the money and don't feel like messing with all the mad scientist stuff check out the biopro 190. It takes a little longer to make a batch but you only have about 20min hands on time, otherwise it's fully automated.
I'm sick and tired of giving my hard earned money to fat cats and terrorists!!
