Hello Rick
As you have found out by now, its very easy to invest several thousands of dollars in this equipment if you've got it to spend.
I think if I was in the position of your friend I would spend that money on a airline ticket to Austraila to visit the clinic of Dr. John Holt who has the only proven protocol for defeating most cancers.
More information on Dr. John Holt can be located on this website.
Best Wishes
