Snowboard Iskola

Does anyone know where I can find a FREE copy of an official snowboard manual for any national snowboard association? (AASI, BASI, etc.) Just looking to save money… Alternatively, if I have to buy a manual, who knows which manual is the most technical or, in other words, which manual describes the most advanced and complex manouvers and techniques?
