(Amazon has some great options available for extra stainless steel toaster oven pans, and a 12x10x1″ is a bit larger than the standard pans for this size toaster oven, but fits it perfectly.) I’d read one review by someone who’d returned their oven because the display sometimes fogged a little with steam when the convection feature was used.
