I'd say Scott's Sonar Power books are more useful in the long term but the Eli Kransberg vids are extremely well done and will get you up and running extremely quickly. The best bang for the buck is to probably pay for a month pass at G3, watch those vids and work through all the lessons while taking notes. This will probably take a few days to really nail. Then you'll have the rest of the month to explore all the other vids. There are some very good ones about mixing with X1 that are still very relevant to how things work in X2.
Cheers.
