Original poster: "Godfrey Loudner" <ggreen@xxxxxxxx> Checkout the amazing bidding for a little dental x-ray transformer that sold for $710. I got for free three of these GE units of the same model from a dental clinic. Actually they are not useful in making interesting arcs. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7602023113.Godfrey Loudner
