i love my iron! can you still use your iron without water? i never put water in mine but rather use a spray bottle (avoid those nasty rust spots). i've tried cheap/expensive ones and really don't notice a difference in how hot they get. but i do use a teflon iron plate cover - and never melted anything . . . scroll down on this link - http://www.tryourdesigns.com/BoNash.htm
my best/all time favorite iron is an antique/super old one (before steam irons!) . . . it gets super hot and it's heavy . . . wish they made things like they used to.
