Cook's Magazine reviews 13 by 9 inch pans. The Pyrex Baking dish is their favorite pan. It costs. $8.95.
The All-Clad Rectangular cake pan costs $94.99 and is not recommended.
I notice on Wedding registries that brides and grooms ask for expensive pans. It sounds like in this particular case picking up a pyrex pan at the grocery store is the way to go.
