Amazon has the Honeywell HEV320 Evaporative Humidifier back in stock in both White and Black for $35.99, shipped and sold via Amazon.com. It is eligible for free shipping with Amazon Prime.
I was looking for these for the last couple days but they were sold out everywhere. These will not last long. Great for people with guitars, cigars, or dry skin during the winter.
