I think it's closer to 2x the cost. Doug's is better quality and puts out more heat but I think it uses a lot more propane. I run mine pretty low, more for atmosphere than heat. I also liked the smaller size.
I've found the little red campfire for $111, the cheapest I can find the CampFire in a Can is $299. I am interested in using it more for ambiance and even roasting some hot dogs/marshmallows over than trying to use it as a heat source. I really like the idea of being able to use it under my awning during a rainstorm.
