I wish I could help you more! I recently bought the dacor discovery duel fuel and won't be able to use it till my house closes in September! I too found it hard to find people who had the Discovery line, but I am taking a chance after visiting several appliance stores and talking to a lot of people, oddly they all seemed to vote dacor above wolf.

I don't have either but I can say that I've never heard anyone have something good to say about Dacor. I'd avoid it just based on the unanimity of people's opinions. That's pretty rare. Also, I was actually kind of excited about the android-powered Discovery appliances. Then I kicked the tires and found that it is absolute garbage. It's running on an old outdated version of the Android OS (I don't remember which) and it allows you to install whatever you want from the Play store with no contingency plans for crashes. Android is far from perfectly stable. It will hand and it will crash, especially if you install apps that increase the instability of your device. These appliances have no contingency plans for crashing. If the Android tablet crashes you're going to burn your food and possibly cause a fire. Also the recipe database was extremely limited. There was one or two options for each kind of food (chicken, fish, etc.) which is kind of ridiculous. It's the clunkiest piece of technology I've seen on a kitchen appliance. Total garbage.

It just seems from what I've read here, there is a lot more trouble with the ovens in American ranges. It seems that the service can be more of a gamble too. If you search American Performer, you can read more. It is the closest in function to the RNB. It has star shaped uncapped burners like the RNB but with a semi sealed burner tray. It might be ok for a range top but I would not want the range. American also has ranges with capped and sealed burners and lower BTUs. Their DF has sealed and capped burners and a fairly simple oven, single fan, with only a standard bake and a true convection mode. There is very little in the manual so I would want to really see how it worked before I bought. If you don't have confidence in a local dealer for BS, consider buying from Trevor Lawson at Eurostoves. He takes excellent care of his customers and has helped some on this forum who did not buy from him.

I am getting a 48 inch gas range top. I have narrowed it down to the Miele with built in griddle (mostly because it matches the Miele Steam Oven and Miele microwave) or the Dacor all burner with removable griddle. I like the larger size grates on the Dacor. I wonder how useful the griddle is and how easy it is to keep clean.
