Hey, just so you know - CureZone sponsor and my good friends at Utopia-Silver recently increased their PPM to 30 (used to be 20) and they have a buy-one get-one free offer for new customers. I think that is a great deal and would highly suggest that anybody who makes their own take advantage and have a couple of bottles around just in case something really tough came alone. You know that they make the really good stuff (true Colloidal Silver with ultra-small particle sizes ranging down to 0.65 nanometers).
I like their Silver Bullet home generator a lot too. It's a low frills unit with a higher voltage generator (48V) that produces a bit higher colloidal content. I wish they had a stirrer, but that is how they keep the price quite a bit lower than many units they outperform - just about as low as the costs for a do-it-yourself unit outlined in the post we are responding to.
