I passed on the information about the MME (couldn't find reference to what the 
intitials stood for) to a health practitioner who uses the Scenar.  She replied 
including the following information:

I have heard Scenar is way better than the Beck machine. One of my customers 
has the Beck machine and she says 5 mins on the Scenar gives her the same 
results as 2hrs on the Beck machine.
