You might keep an eye out for a nice pre-owned unit (Thermador, Wolf, Viking, DCS, Gaggenau, Elecrolux, Dacor, BlueStar, Five Star, etc.).
If it fits the bill, this Viking seems like a good deal (and shouldn't be too far away):
Viking 48" Gas Stove / Range / 6 Burners and Grill(syracuse)
Here are a couple good deals locally in PHX (even considering freight):
