Has anyone ordered one of these? I saw an artice about it in today's USA Today stating that if you call within the next 48 hours, you will get the fireplace for free as long as you buy the mantle ($300) that goes along with it. I called the number and it sounds authenic, but I am still a little hesitant. The article says it uses less energy than a coffee maker but will heat an average size living room in minutes. I thought about ordering one to cut down on my lp gas bill, but am not sure. Any thoughts?
