Hey Lisa, join the dark side!

Take a look at the last 3 or 4 posts in Jon's Journal, there's a load of information about BFL he posted to some questions I had. Very helpful. If you decide to give it a go, I have the excel files he talks about and some other stuff that would help you. The book can be bought at any bookstore around town. Kinda pricey though, only found the hardcover (not even sure if there is another version).
