I am still looking for a BECK "BRAIN TUNER" to experiment with and am
willing to trade a Beck model Blood Purifier for the use of one for a month.
Will return it at my expense and in the identical condition in which
received. Guaranteed. Sender keeps both devices.

Scott,
  I will get mine out to you.  I tried to reach the doc that gave it to me
but he seems to be on a long vacation, which I know he does from time to
time.  If you would like to tell me where to send it I will get it out to
you and you can see if you think It is the model you would like to test.
Thanks, Donna
