The Rife Digital Ultimate - opinions please!

I'm wanting to purchase in the near future the Rife Digital Ultimate from http://www.rifedigital.com
and would like know if any of you have bought this unit which costs approx. $531 and your opinion on it?

It appears reasonably priced for all the technical scope it offers when compared to the other more expensive rife units.

Also I wondered whether the Rife Digital Ultimate has a facility to use in unison with the SL-1 unit - which I presume is called the Magic Bean - as although I don't mind using the contacts on both hands and feet, it would be preferable if there was a way to get the frequencies through without using the leads.

I'm new at this but vaguely have an idea that this can done, perhaps someone here would enlighten me, with thanks in advance!
