Use the code DIWALIGIFT to get the course for free. Their Twitter post says it's free for the next 72 hours. They posted on October 16, so the code may expire today.
I can't speak for the quality of the training yet, because I haven't started it. But if it's free, what do you have to lose but a little time?
