I recently purchased a Branson 3510 and it came with a full tank. I decided to use B100 immediately and have been replacing the regular diesel as it it consumed. I'd say the mix is most likely 40% biodiesel right now.
For me, I'm just plain tired of smelling #2 diesel. It's not like I smear it everywere, but re-fueling has been a pleasant experience. Performance of the engine has been just fine.
There is quite a bit of information about biodiesel on the web, some good (like www.biodiesel.org), and some just plain wacky.
I buy the biodiesel from a local distributer who buys from one of the large biodiesel manufacturers in the midwest.

Right now, from what I have seen on the net, it maybe less expensive to purchace than diesel fuel? Why does the Gov. expect tax money from a fuel that is better for the inviroment; new technology less money,I don't under stand????
