There are humidifiers, and then there are humidifiers. The Stadler Form William Ultrasonic Humidifier falls distinctly in the latter category.
What makes this fancy humidifier worth $230? Well, it "can cover up to 1,000 square feet, and features an on/off time, a sleep mode, a turntable mist diffuser, an Ionic Silver Cube to ward off bacteria, an integrated hygrostat, and a maximum output of 3.5 gallons per day." Also, it's pretty damned stylish, which doesn't hurt. So if you're sick of waking up with dry skin and a dry throat in the wintertime, this could be a good solution, albeit an expensive one.
