I have a full size Rowenta that I have used for over 15 years and I bought a travel size Rowenta (purple handle that folds) for Quilting when I go to workshops. I love both of these irons, but a friend that quilts swears by the Sunbeam iron.
I think it is a matter of preference. But remember, when quilting, your iron is on most of the time. It does get a lot of use.
