Yup, the "31 Days To A better Mix" series is one that I recommend a lot, and I own all of his stuff except for the REthink Drum & Room ones. He does teach from a "cookie jar on the bottom shelf" perspective which is real easy to follow.

He even has a 6 hour series called "Rethink Mixing" , but I feel that Audio Mixing Boot Camp is far more organized & informative...sorry Graham!

It all depends on how you learn, videos or books, classes or self instruction, or others advice...just pick one & go for it!

PS-Just use the plugins that comes with your DAW & the equipment that you have now, no $$$ needs to be spent up-front really.
