I'm very tempted by the All Clad 12" skillet with a cover that's selling at a promo price of $90. But I need some feedback ... I know there are many AC fans on this site, and this would be my first piece, but I'm afraid it's overkill. I already have a 10" Calphalon stainless steel (though it's old and I don't know if it's tri-ply) a 10" nonstick (both have glass lids) and a 11" Lodge enameled cast iron skillet (no lid). I'm sure I'd find use for the AC pan, but given space is at a premium in my tiny kitchen, I'm curious to get your thoughts on whether this additional pan is REALLY worth it ... or if my money and cabinet space is better applied elsewhere. I'm in your hands, Chowhounds!
