Hi
I have been studying and using trance states personaly and professionaly since teh early 80., and started meditating in the early 70s.
Part of my study has been the use and development of entrainment methods, like the ones you have seen advertised. These technologies can work, but I can not speak for the quality of most of them.
Ultimately it does not realy matter if you choose to meditate formaly,or use entrainment technology. Some of these technologies are contraindicated for people with epilipsy and some other disorders, so if that is you , get professional advice first.
Counseling is very useful. So is hypnotherapy. These recordings are terrific, I am a big fan professionaly and personaly. Try Anxiety Free, Self Esteem Supercharger, Belief, etc.
Entrainment, if it is well done, is a fast way to get to useful states. Vipasana is a long and arduous road, and is religeous too. Spiritual practices have been proven to help people with their physical and metal health! That has to be your own inner choice.
Entrainment technologies that I have come to respect include Centrepointe (used in the paraliminal recordings), Anna Wise, Jeffrey Thompson, and some of Robert Monroe, though he gets pretty "far out" for me alot of the time.... I also like Alpha Stim for some things, especialy drug addiction.
Whichever method you choose, be prepared to give it time, the real benefits come from consistent use over time. (Exception is hypnotherapy, it is solution oriented and can achive alot in relatively short time, ie days-months compared to years-decades)
SOrry I cant choose for you, I like them all for different reasons. But here is some information that hopefuly will help you to make your own choice Go with a good company if you choose entrainement.
