I have a book with fishbowl production in it. It might be a different version, but still, I think you can find methods availible elsewhere. To me it seems that all you are paying for ($300 +, yikes!) is the method and the little zippered production bag.
I would hate for you to kick yourself after you got it when you learned that you could have done the production on your own without paying $300. The book I have is called "Great Tricks from the Master Magicians," and was published by Golden in 1979. I'm sure there are others out there.
Good luck! and if you do get it, let us know what you think, and if it was worth it!
