My 2011 Self Cleaning Natural Gas
Whirlpool range did not ship with a broiler pan, either. I bought one separately, but rarely use it. Someone here, maybe joeekitis, suggested using a shallow Corningware under the broiler, and I have been very happy with that. Very happy. The only times I use the standard broiling pan with rack now is for bruscetta/garlic bread and other toasting sorts of dealies.
As for "Aqua Clean," I think it is a giant Deevolutionary move! If I were in the market now for a gas range, I'd go either for GE or Frigidaire.
