Need suggestions for baking dishes to make individual pot pies. I can't seem to find any Corningware 16oz ramekins in stores.

I have a 16oz Corningware Ramekin that I like but I only have one. I need a couple more and I can not find any in stores. I know that I can order online but I figured if I have to do that, I might as well see if there is something different out there. I did come across a Corningware 18 oz appetizer dish in the stores. I assume that may work. I have also come across Fiestaware Casserole dishes and some generic porcelain dishes at Target.
