Woot offers Amaze-Heater 250-Watt MINI Convection Room Heater for $79.99. Free shipping for Prime Members. 

Product Description:
Amaze-Heaters are the safest in their class as there are no moving parts with no gas and no exposed heating elements. These heaters will allow you to save up to 50% or more on your heating cost. Instead of heating an object or person, the heater uses efficient convection technology to warm an entire room up to 80 square feet depending on room insulation. Its ultra slim and compact design allows for discreet out-of-the way wall mounting and installs quickly and easily with the included installation hardware. Once installed, the heater can be painted to match the room decor and will operate silently. As the heater will not dry the air or burn up the oxygen in the room, you will experience warm, comfortable, efficient, safe and silent heating all season long.
