I have been using the Allied Metal BB series pans for the past few years for Sicilian style pizza and like the quite well. i was thinking of adding a couple more until I saw that the price of the 12 x 18 is up to about $70/half sheet (unless one purchases a minimum of 6, at which time one can purchase directly from the company at about $35). The Lloyd pans are about $35, but are made of aluminum as opposed to steel. Does anyone have any experience with both types of pans? I would be interested to know the difference in performance between the two to determine whether I will pop for the Allied. Or if there is an interest in a group purchase, i would be game for that on a cost + shipping only basis.
