I just bought the one from Ripple Training. Honestly, I am pretty disappointed. It doesn't do that much with 3d and lighting, the design stuff they work with is mediocre and they don't really get into anything that is very advanced. If someone knows of a resource that is like videocopilot.net (only for Motion and not AE) I would gladly be on board to buy it.
Too bad we have to hear the annoying click sound at a loud level from the teachers keyboard. Don't the ;isten to their finished recordings before releasing the tutorials? I guess there is a price for something that syay it is free. :-)
