I've been a Taebo fan for years and unfortunately, his original live series, both Basic and Advanced, are not available on DVD, and are scarce even on VHS. They were the best! Had the greatest music too! They were live and featured real people along w/Shelli and a few other expert Taeboers, that was part of the charm for me, as well as the GREAT music. SO inspirational!
I'm not as impressed with the Goodtimes Taebo, but I don't have the Bootcamps yet and I hear from other oldtimers like me, that they're worthy.
So if you're experienced, get the Ultimates, they feature the best of the old Advanced Live series, if not, get the "Get Ripped" series which I believe has an instructional workout included.
Billy is just the best! Enjoy!
