These devices are sold by Peter Gamma from www.petergamma.org. If you find an EEG device at
Cody Rall MD with Techforpsych, go for it and buy it. But Peter Gamma from www.petergamma.org prefers to build his on personal EEG device, due to the miserable situation with EEG device. So every meditation teacher at the highest level has to build up his EEG device by himself.
