I have a small iron (I do use it for classes and it's great), however, having a heavy steam iron works so much better pressing seams and blocks. I bought a reproduction of the original GE iron. LOVE IT...it does have auto shutoff because its new and its a requirement for new regular irons. The weight is great as it really sets the seams and my blocks look better. One thing, I wouldn't spend more than $25 for an iron. All the cheaper irons like Black and Decker have worked great for me. Good Luck
