Though not strictly an EMG unit, I saw the Cyberlink being used by a local
CP chap. It seemed surprisingly reliable. Tensing the forehead seemed very
reliable as a switch input although I don't know if the sensing is EMG. Eye
movement (presumably EOG) seemed OK too. Cyberlink also divides EEG into
band & calls it "brainfingers" which my contact could use for proportional
control - but with difficulty.
