I bought a Euro Steam Evolution at the quilt show that I really like. It's an internal boiler iron so the plate doesn't get too hot. I can iron silk and poly with it. It puts out loads of steam. But it's still not the perfect iron. I also have an early 60s era GE dry iron I bought "new in box" on ebay. I have them both on my ironing center.
For those of you that keep knocking your iron to the floor, maybe you need to get a more stable ironing board. I haven't knocked an iron off the board for at least 8 years since I bought one of the wider boards.
