I bought an expensive iron from a quilt show vendor called the EuroSteam. I like the fact that it doesn't sit up on end like most irons. It rests on a Teflon pad and doesn't shut off after a few minutes like most. This saves alot of wrist action. I have carpel tunnel, and anything that minimizes wrist movements is worth it to me.
The one I had before this is an inexpensive Shark. It worked fine too.
