The colloid model is at www.wishgranted.com.  The Colloid Master has a kit 
which comes with a distiller.  Both of these seem like much better units, 
please give me any of your opinions.   

**** Hi Lynn.  I have a Colloid Master, and have used it on a daily basis for 
six or seven years now, with absolutely no problems whatsoever.  It produces 
nice, clear CS at the ppm-level that I select.  I'm not familiar with a kit 
that comes with a distiller, so I can't respond to that -- but I think you'll 
be happy with the Colloid Master itself.  MA
