I got one from Home Depot (do not remember the brand right now). It has a small heating pad and it actually puts out steam instead of using a fan. It is fairly quiet, and it is very easy to maintain. You just have to fill the water tank when needed, and about once every month or two rinse it out and replace a small filter pad (its about the size of a drink coaster). You can set the desired humititly level and control the output rate. It was about $60 I think, and from what I can tell should last many years to come, as the only thing that gets scale build up is the replaceable pad.
