I wonder if the higher priced ones are better. I can't imagine how because the one I have is bottom of the barrel and was around $20. I have started to figure out how long I need to cook the steaks available locally and yesterday I made one about an inch thick and just five minutes in there at max setting (200 degrees C) was still a little bit too long. I enjoy medium rare that is more on the rare side, so I guess the next one I will only cook for 4 minutes
