How much does a Harmony evolution cost?
Not an easy question to answer because most of the benefits cannot be easily quantified in monetary terms.
One can look at it this way:
If you pay for your own medication (which most of us, at least partially, do nowadays) and the Harmony evolution first dramatically reduces the amount necessary and then completely eliminates it, how long does it take for the savings to exceed the cost of the Harmony evolution?
How much would you be willing to pay to be pain free, more intelligent, happier and more relaxed?
When it all boils down to it, it's simply a question of how much 10 years of continuous benefits is worth to you.
