I saw the model at the store had a warming rack included which is one of the reasons I purchased this grill. But at purchase, I see there is no warming rack??? What did they use that would be universal. I love this grill!!!! It is heavy duty and much more stable than other brands and just as portable and convenient to use as the competitors... but why show the model with a warming rack when it don't come with one? Where can I get one. I really like to use warming racks after I have my food seared.
