Sounds like a scam to me, I can't imagine paying for any of those. My bet is that the commonly available hemi-sync files and programs like BrainWave Generator combined with the right mindset can accomplish just as much as any of those pricey discs.
I always hesitate when there's a price tag like that and no way to know exactly what it is you're getting until you pay.
