HI Heron
IPM is a delightful, single session, CD, I believe, that LSC, have phased out, the Tapes, and made some improvements, by re-mastering, the paraliminal’s and adding Holosync tones, if I remember IPM is only 25 minutes long, Should you buy NBG, only you can answer that question, if your unsure, then just get IPM, give it a test drive, if it works well for you then there is nothing stopping you from, Getting the new behaviour generator, or you could get them both, as there are covered by a 30-Day Money-Back Guarantee, so which ever way you decided to go, you’re a winner.
Hope this is helpful.
