the lasko 5812 space heater costs about 30.00 and heats up a good area.  i use my lasko heater in my den in the winter and it really takes the chill out of the air. it has a shut off signal so that if the dog or one of the kids bump into it the heater will shut off automatically because it has a tip over switch.  you can also adjust the level of heat you want from low to high  its not low--high switch its more like low and then about ten dots to high so you can adjust it to  whatever your comfort zone is.
