I've never had an iron cord curl either. Having said that I have a new iron that has a nice, long cord.. got it at Walmart (purchased online and picked it up in person)

I really like this iron and the cord is long which is awesome. My last B&D had a much shorter cord... and this iron has almost double the wattage as the last one so it gets hotter and does a better job all around.
