I recently bought two cordless irons from a local supermarket (Lidl - German and great quality). They were 15 euros each (around 20 USD).
You can either use them corded or cordless and they sit on a base unit with the heat plate protected. Cordless, you can iron for about a minute before they cool down which is great for pressing seams. When you put it back on the base unit, it heats up again in about 20 secs. You can also lock them to the base unit which is a great safety feature when the kids are around. I have one up in my sewing room, plugged into a switched socket specially installed by DH, and i switch it on when i go in there and off when i come out, almost without thinking about it! The one downstairs is for hubby shirts and doesn't get much use at all! :mrgreen:
