I have a Panasonic NI-L750SR 1500W. I've been using it for 14 months and absolutely love it!!! It never has a problem staying hot. As quilters we rarely iron great amounts of time anyway and I've found mine can go nearly 10 minutes before needing to heat up. That's rarely a problem, because I'm setting it down often enough for it to stay warm. It has wonderful steam too. I wouldn't trade it for a corded iron for anything!
