I agree. I have seen the cool mist evaporative types for under $20 online, or a pharmacies like Walgreens.
Hey, if you think your MIL would appreciate the effort, be a hero of a DIL and buy her a little cool mist humidifier. You don't need to mention the fire risk, just say that it may save her some on her electricity bill (which it probably will).
