It looks like the SteamFast only has 1 temperature and is 1200 watts. Panasonic cordless models have 3 temperatures and are 1500 watts. The Panasonic models should be able to reach a higher temperature. My cordless is an older Panasonic (not the 360) and works great for quilting.
I don't iron clothes, but I do make draperies. I use a portable steam generator (Reliable brand) for that since it requires much more steam to press bulky pleats and upholstery fabrics as well as set adhesives on buckram. If I had the room, I'd get a Laurastar.
Thanks for your reply. I also appreciate your tips on draperies. I have a pair on my ToDo list.
