The second edition comes out this year so you may not find it; however, the first edition is available at interlibrary. My friends and I borrow it last year for months. Ask your local library to loan it for you. If you want to save big bucks for the first edition you can contact Professor Arditti (he will refer you to his brother who still has many copies of the first edition). If you have question you can ask him at orchidspng.com and he's very friendly.
