Anyone here ever used them, heard of them? I got a sales rep. coming to my town to go over what they can offer me. Not totally interested and I'm pretty happy with what I'm already using. But the guy's been very nice and very persistent and offered to buy me a lunch to discuss it. So I figured I'd hear them out at least. Just curious if anyone here used their products or bought from them. If so, what's been your experience? http://www.coppermoon.com/index.html .
