I can only remember checking one out at a Pfaff dealer years ago. Pfaff decided to sell gravity feed irons and an ironing board with a fan and heat. Apparently they didn't sell too well, I got the board free a couple of years ago. Fan and heat still work. The iron is lighter than the Steam Generator but you need to hang it and then you have a hose connected, too.
Allbrands sells Reliable and other gravity feed irons. Check their pages, some do have reviews. Here's a link to a Consew and there are some reviews at the bottom of the page:
