I have a Rowenta, have owned it for several years and I absolutely love it! I have owned Black & Decker, Proctor Silex, etc. They did not work well for ironing wrinkles out of fabric. My opinion is you need to find an iron that has good weight to it. The B & D and Proctor Silex just are not heavy enough to remove wrinkles well. I think the weight of the iron has just as much to do with the performance as the heat does. Go out & compare the weights of different irons and you'll see what I mean. I had a Sunbeam that I got as a wedding gift back in 1975 and it worked good as well (it was good & heavy), so maybe a good vintage iron would suit your needs.
Hope this helps,
Becky
