Groupon Goods has this manufacturer refurbished Pure Guardian 144-Hour Ultrasonic Humidifier for only $49.99 – value of $149.99!  Free Shipping and Returns.  Limit three per person; additional two as gifts.  These are invaluable during the dry heat winter season – we need to replace our tossed ones.  This one says either cool or warm mist settings – I’ve never seen both options on a single unit!  Sad that this gets me excited…
