Video Value...
I was lookin for some as well and the 'vibe' I got was that there are only one or two that are worth the money. IF you look at the production dates of the videos and the improvements made to the planes (9 in particular), you might find they might be a little behind.
While any one nuggett of knowledge may be worth the price- I was steered towards a weekend or week long RV build class to get a feel for the process.
Best of luck-
