I went to the Copperhill website and tried to order a cleaning kit, but when I filled out the purchasing page, it said my email address is not valid. What the H___? I have been using this addy for 2 years, ever since I got a satellite hookup, and now they tell me its not valid? Do any of these sites ever hire webmasters that know what they are doing? So my question is, where can I purchase the cleaning kit (basic for 20D)? I have other methods of cleaning but wanted to try the Copperhill as it is so highly thought of here.
