Does anyone have any experience with the NewAir brand? I haven't heard a lot about them, but I have been looking at some of their products and they are the most affordable I have found. The reviews seem to be positive as well, but I'd really appreciate some feedback if anyone has had them/has one now, etc. I'm most interested in right now, but I'll need a few space heaters for the winter too. Other recommendations if you don't know NewAir would be helpful as well.
