I have a silverwell Colloidal Silver maker for sale, but only for australians due to payment and postage costs. I have used it less thatn 5 times. and is in excellent condition. If you want to see what type it is then go to web page http://www.colloidalsilver.com.au/.
Email me at firstname.lastname@example.org if you are interested.
I tried to sell this device on ebay was not allowed due TGA restrictions. I don't know where else to advertise.
