Walmart offers the Duraflame 5,200 BTU Infrared Quartz Heater with Ember Bed and Logs for $102.50 with free shipping. (Amazon charges the same.) That's the lowest price we could find by $6, although most sellers charge at least $120. It heats spaces up to 1,000 sq. ft. and features an adjustable thermostat, LED flame effects (that work with or without heat), and remote control.
