We got this little ceramic heater from Target.  The price was very reasonable - under $20.  It really is a little wonder as to heating space - has a good fan that gets the air moved out.  It is not energy efficient - we popped the circuit breaker the  first time we plugged it in so have learned that we can only use it with minimum other electrical items at the same time.

It does not automatically shut off when it tips over - as we have a dog in the house this is a concern for me.
