I am trying to choose an EEG machine for personal use, and have narrowed down my choices to between a WaveRider and a Brainmaster.
I was wondering if any one had experience with these, and had recommendations on which is a good one to buy. The recommendation can be for a completely different machine.
My second question was if having 4 EEG channels gave significantly more information than 2 channels, and if it was worth the extra cost.
