Some of you are probably aware of this but Centerpointe has some competition from the folks at Awakened Minds
http://www.awakenedminds.com/ There is only ONE CD and it costs less than $40! Now this beats 12 levels at under $300 per level. Might be worth looking into...
"How do the Awakened Minds audio CDs differ from the Monroe Institute's Hemi-Sync tapes or Centerpointe's Holosync program?
While the Hemi-Sync and Holosync tapes use binaural beats to induce specific brainwave states and we applaud them for helping to make binaural beat technology more well-known, we feel our audio technology is superior to that used by other companies offering similar products. Our Insight CD is vastly more affordable and, due to the use of harmonically layered frequencies, we believe our audio technology is more powerful and effective. The Price & Quality Comparison page of our site provides a more detailed comparison and includes a comparison chart."
