A really cool piece of technology that gets metal things very hot very fast. I first saw this on YouTube and have been watching it for a while -- this is by far the lowest price I've ever seen. It retails for $649. Here's a marketing slick [theinductor.com] on the product, from the manufacturer, if you're interested.
