Also level 3 members get a montly CD disc mailed to them every month. The lessons on these discs will frequently get packaged as a new course at a later date. (Many of Brad Carltons courses have been like this).
As to whether it's better to buy the individual course or to become a level 3 subscriber. Can't really answer that. Pros and cons to both. It's entirely up to the individual and whether you like to cherry pick lessons in alot of different styles or whether you want to just focus on 1 course at a time and maybe even how much time you have to practice.
