I usualy dont just barge in but I was reading the post and thought the web sites may be helpful or at least explaine a little.I am NOT promoting any product or site, just sad that out of the whole u.s.a. me and 1 other are the only ones who have a stim. it is a shame people do not know about what is really out there . no harm intended posting the links.
Peace everyone!
