Welcome Buzwak! I too have done TM since the 70's. Most recently I did a couple of levels of Holosync but chose project meditation as an equally good if not better product with a very active community (which I like) and it's less expensive too.
Additionally, I own the Mind Workstation which is software that a lot of counselors, coaches and therapists use with their clients for brainwave entrainment and while there are many pre-written programs for various specific purposes such as treating depression, you can also build your own.
