Anyone bought either of the Digital Art Live training modules by Esha?

For want of decent manuals, I'm always on the lookout for more efficient ways to learn my way around Daz Studio (rendering as well as content manipulation/creation). I've been picking up bits and pieces from the forums courtesy of some very helpful people along with free and paid tutorials by Sickleyield, Ironman13, Dreamlight and others. 

I'm curious to know what impressions anyone has of the training modules by Esha, in particular the Foundation and Mastery Part 1 products. 

Thanks!
