In addition to my Rowenta's I have a EuroPro iron that I purchased at a quilt show years ago. No auto shutoff, huge amounts of steam (does require distilled water). It was expensive but it has been a great iron.
I agree with the suggestion of the iron plugged into the same source as your light. Myself, though, I always unplug my iron whenever I leave the area. I iron clothes as well, so have a couple of different areas where I iron things. As well as having animals. I'm always afraid that one of them will walk by a cord and pull the iron off it's surface and possibly turn it on. Thus unplugging each time. And my fireman DH really appreciates the habit!
