I bought this little item this morning at the most expensive hardware store in Boulder Colorado, at $55 it's a steal.
It runs at 700 watts maximum which enough to take the edge off when using the over priced power in a CG. We have the larger version but this one is 12 long 14 high 4 wide plus the feet that are 6 inches across.
We have never been comfortable with propane exposed flames and gases or the open element electric heaters
