I went online to order a copy of Robert Von Maier's Solo Diving, and discovered there is a new Solo Diving Revised, released as of January 2007. It's a fair bit more money (twice as much on one website) compared to the original, and requires a longer wait on ordering. So the question is, does anyone know if there is any substantial difference between the two, that justifies the wait and expense, or should I just get the regular one?
