My last iron I bought cost me 12 dollars. It's a Proctor Silex one. I don't use water in my irons, if I need some steam I spritz the fabric. Less chance for it to spit rusty colored water onto your white fabrics. It heats up well, I should know by the tiny burns on my wrists. I have owned a few of them they are good.
I have owned Black and Decker irons too, those are good ones also. Sunbeam is another.
I have heard horror stories here on this forum about Roweta irons. They seem to catch on fire at will. Now for a 100 dollar iron you should expect it to not do this.
Nothing you are going to buy nowadays will be as well built as your current one.
