Cooktop 30" Gas 5 Burners

[Sirfunsun]

Hi,
Cooktops 30" Gas 5 Burners at a low price are hard to find at a low price.
My wife is Chinese and she would like to have that high BTU (high heat) burner for cooking with a Chinese wok.

Anyone have advice or direction on where to find a great SD deal to buy a Cooktop 30" natural gas with 5 Burners?

Thanks,
