I wish someone would write a soaring book on flight computers. How to choose one, program, trouble shoot them, use them. Combine book with YouTube explanations.

Chris,
The easiest, least expensive choice is to use XCSoar on an Android phone or tablet. That said, I have lots of questions that are not covered well in the manual and I am forced to either ignore certain features to try to understand them while flying. A good video tutorial would be really helpful.
