The Gentle Wind Project makes a big deal about it being a nonprofit
organisation, and use of their instruments is supposedly free, but GWP
requests donations anywhere up to US$20,000 (NZ$33,000) for the instruments.
The most expensive instrument on their web site is US$7,600 (NZ$12,500
– apparently on special from US$8,600/NZ$14,000).
Anecdotal evidence of the amazing effectiveness of these instruments
is the typical "this product did wonders for me" sort of thing
that's used for everything from selling cars to old mouldy cheese and
bee pee (no offense to bees). Apparently users can become so dependent
on the blocks of plastic and metal that they eventually cannot function
properly without them. The use of the "healing instruments"
can become a habit (clinically known as a dependency) that can be very
hard to break.

From a Gentle Wind Project web page:
Each employee works between 72 and 84 hours each week,
for 365 days of the year. ...
Project employees have no time for recreation ... Most
employees have not had a vacation in more than twenty years.
Former members claim that employees often work for minimum wage, while
many volunteers work for free – often putting in so much time that their
own businesses suffer.
Compare this to publically available tax details (see More
Information) which show the top six leaders (John Miller and his
five-woman "harem") were in the 2001-2002 American tax year
each paid a salary of US$52,839 (NZ$87,000) in addition to having
all living expenses, transportation, housing, travel, food, and cars
paid for. Boats and other recreational equipment are also included for
these leaders – something GWP claims its employees have no time for.
For example, in their 2001-2002 tax return, they list "Research
– boat $66,979" under Other Expenses. (At time of writing US$66,979
is about NZ$110,000, although due to a high exchange rate at the time
was then worth up to NZ$160,000.)
In the same year (2001-2002) Paul Carreirro (the brother of two of
the directors) was "loaned" a total of US$204,865 (about NZ$337,000)
for medical care. All three "loans" are interest-free with
the repayment terms listed as "ON DEMAND".
Update: The 2002-2003 tax return shows the five women directors were
each paid a salary of US$71,799 (NZ$104,000). Their titles are now President,
Treasurer, Clerk, and two Directors. Strangely, John Miller is not listed
as receiving a salary. The 2002-2003 period is before GWP was revealed
as being a cult/scam, although the return was filed several months after
the revelations.
Update: The 2003-2004 tax return shows the top five's salary was US$70,270
for that tax year. Once again John Miller doesn't appear in the list,
but one of the directors is also listed separately as an employee who
was also paid the standard US$70,270. Legal fees for that tax year are
listed as being US$110,769 – that's over NZ$161,000 at time of writing.
(The previous year legal fees had been US$2,407, and nothing at all
for the four years before that.) The amount devoted to Medical Research
& Grants was an amazing US$448,838 – amazing since they can't provide
even a single scientific study to show their healing instruments work
or are anything but coloured paper, plastic, metal and 
sand.
