I got so tired of the name brand expensive irons having problems over the years that I now buy the cheapest shiny bottomed, steam iron from Walmart -- usually around $20 +/- -- and throw the dang out when it begins to sputter or give me other issues.
I started out with 2 to have a backup, and when 1 died, I went right out and bought another. Now there's always an extra on the shelf; I just won't put up with that frustration of having no iron in the middle of needing one -- usually after 10 at night or on Sunday evening!
