I've been fascinated by all of the articles posted on here about tDCS, so I definitely signed up. I'm willing to pay $99 for a device that's probably worth $10 in parts, so long as its easy to use, easy to assemble, and works. Besides, if it works, I wouldn't mind starting my own business selling pre-built tDCS machines.
