Thanks Mary for your message. I am still contemplating. Also I found out that to identify correct frequencies F Scan Compact is also good choice. As I mentioned I am going for my biocom first session tommorow. Lets see how it goes and then I will decide which one to buy.
...meant to say he believes the Perl will be the best one not the rife!!! lol
Thanks Verma!! I have recently spoken to naturopath here in Adelaide where I live and he has 3 different rife machine's, one being the M.O.P.A with the GB 4000 and the Perl. He is going to let me try all 3 at no charge to see which one is better for me.....how nice of him, he is very helpful and I haven't even met him. He believes the rife will probably be the best but wants to try them all on me to make sure. So obviously I have made a pretty good choice with the Perl then.....maybe you should consider too!!! Best of luck
