I have been making CS for a few years and I'm now interested in making 
colloidal gold. But a search of the archives and extensive googling shows that 
gold 
generators are few and far between -- and expensive. One of the less 
expensive, which is said to produce both silver and gold is on sale at 
http://colloidalsilvergens.com/generator-info/colloidal_gold_generator. htm  

The sales report says it can produce "40ppm and higher with a new 4" 
electrode which is 90% .999 gold and 10% .999 silver."

Has anyone had experience with this machine?  Comments would be appreciated.
