Next to my sewing machine(s), my vintage GE steam iron is my favorite tool in the studio.
I've probably had four of these in the last 30+ years and I love 'em! I always find them at thrift stores for about $4.00 and they are a work horse. It heats quickly, stays warm a long time after it's turned off - an added benefit to my mind - and steams like a tea kettle. I know a lot of quilters avoid using steam, fearing it will stretch or distort the fabric, but I've never had a problem.
I've tried a number of other brands over the years, including Rowenta, but I don't like an iron that's made of plastic or that turns itself off. I like the iron to be hot and ready to use when I pick it up. Sometimes the old version of a tool is the best.
ETA: I just Googled this iron and it's from the late 50s. I saw some selling on eBay for 35.00 and 95.00!
