Hi, welcome. My favorite site when I was new was silvermedicine.org 

and there is still much really good info at fugitt.com/cs

I use a home made generator and batteries, but if I were going to buy one I 
would buy the silverpuppy.

I use a hanna COM 100 meter to test the purity of the water before I start, and 
I bought and tested many different brands of distilled water before I found the 
one that is reliably pure for my area.

The consensus here seems to be that electrically isolated silver produces a mix 
of colloidal and ionic silver, mostly ionic, and that it works the best, and is 
the lowest cost. As you have seen, there is alot of advertising claims made 
that conflict. But an ion is the smallest possible size of any element, so the 
arguments about particle size are somewhat ridiculous.

Have fun reading!
