I'm also a fan of my Panasonic cordless. I've had it about 3 years and it's still going strong. I purchased a back-up Panasonic when Walmart has some on clearance, but it's still in the box.
Before the Panasonic, I used a T-Fal Teflon coated corded iron that was around $25 and did great. It's now the back up to my backup.
For thrums question about it turning off too quickly -- that is offset by it's ease of use. I know when I will need to iron and get up, turn it on, and go back to what I'm doing about a minute before I need it. My iron is the older model with a flat side, but I will say I always put it back in it's base to re-heat and not set it on the ironing board. I don't think the points on both side would be a show stopper for me.
