In need of pan

I'm looking for a cake pan with the depth of 3" (one that I could bake the whole cake in). I'd prefer a circular one, but would be happy with a square one too. It's for a birthday cake that I'm making this week and I think it would be easier to decorate if the cake was one solid piece rather than 2 layers. If anyone has one that they could lend me, I'd greatly appreciate it!
