Hi there, I'm having trouble with finding out which Le Creuset Au gratin dish holds 2 qts. I'm trying to pick one up on eBay to round out my au gratin collection and there are conflicting volumes in the descriptions. I even emailed Le Creuset and all they would say was that they no longer make a cast iron 2 qt dish! Can you help me? I know I'm going to have to buy used but don't want to get the wrong size.
