You will like the T2 (Terminator). The orgone, crystal, and 15Hz combo produces a calming effect, vivid dreams, and sense of stability for any user - regardless of any parasitic issue.
I do highly recommend the CC1. It offers several frequency options, including Don Croft's (the T2). If you are not seeing the results you'd like with the T2 (which I suspect will be the case) and can afford the CC1 - do order. David is great to work with, and I know you will be happy with the quality of his unit.
