• Is there a comparison chart to clearly track the differences between older versions and this one? I am very interested, but I first want to make sure that I understand what new details (topics, skills, tools, videos, etc) this investment would address. Thank you.
    1. Great set, highly recommended... To be honest, I'm surprised that it used to be priced lower then other sets of comparable length & depth. I'm a fan of cheaper prices (and generally hold out for good sales myself), but I also must say that the authors of these volumes deserve their pay (assuming that the increase makes it's way back to them). They have provided an excellent tool, well worth the investment!
