I have the little Sunbeam too. It has teflon on the bottom and stays hot for as long as you have it turned on. I got it on Amazon. My tiny issue with it - the cord coming out of the iron is not in the best place. If you're not careful standing it up after using it, it can flop over. Just because that big cord attachment is so close to the edge and the iron is small. I just used my iron for a 5 day retreat and it worked great.
