F CB, IMHO, the AFT course is well worth the $400. It's not just the course notes that are helpful but the practice CyberExams as well. Four practice exams (which you can do twice) plus the exercises at the end of each chapter, plus email or telephone support from AFT all for $400.
If you buy the books from other suppliers, you get just that .. the books. (Not sure about Rob Averys books whether they include practice questions, but I do know he sells his ATPL exams questions as a separate enitity as well).
AFT is well worth it!! Just Do It!
