My favorite iron is a Durabilt Travel iron (circa 1950) that I bought on ebay. I haven't used anything else since I bought it. There is no auto shut-off, which is a little scary sometimes with my bad memory. It is not a steam iron, so it never gets rusty. When I need steam, I do like Grandma used to do, grab a spray bottle with water in it. This iron is lightweight for traveling, but still has a little heft to it.
Good luck with your search for an iron that is perfect for you!
