After reading all the boards here, while lusting after the high end yellow Osilo, I decided to give a very inexpensive Sunbeam a try from WalMart. It takes 30 minutes to shut off, is light weight, but works like a charm. Best of all it was under $18.00. What I really wanted was the 30 minute shut off while I was quilting. I have stopped putting water in mine though and now just use a spray bottle.
