Based on research I've narrowed my choice down to Wolf vs DCS, both 30 inch dual fuel. However, we haven't been able to see a DCS in person. Fisher-Paykal, the manufacturer, offers no help on its website and amazingly, a phone call didn't yield a useful list of dealers either -- the places they suggested either don't carry DCS or don't even exist anymore! We live in Worcester, and would love to find something less than an hour away.
Oh, and if any of you have input on the DCS vs Wolf issue, I'd be happy to hear that, too. Thanks.
