Colloidal Silver Health Benefits

Hi, I saw on one of your YouTube videos that you recommend buying the SilverTron Elite Generator to make colloidal silver at home. I tried going to their website to purchase one but it said that their website is under construction. Do you know where else I can buy one or do you recommend another generator that I could buy to make colloidal silver at home? I appreciate your help and everything I have learned from watching your YouTube videos. Andrea
