I'd suggest reposting in the Appliances forum.

Meanwhile, I have an oven-under-cooktop arrangement. It works fine, but the only reason I did it was that I wanted an induction cooktop, and there wasn't then available a range that would suit me (the few that were available at the time had a "riser" in the back, which I don't like. Now there are some slide-in induction ranges, which is what I would do if I were remodeling now).

I don't have any advice about the range but you might get more specific responses if you post the question in your title.

I have a 36" All Gas Bertazzoni now and have cooked on it for 7 years. I like the burners, hate the oven. We are in the midst of a kitchen renovation at a new-to-us home and I am not even considering another Berta. I am going with a Wolf this time, and am in the process of deciding b/w All Gas and Dual Fuel. I have a recent post over in the Appliances forum about this and it contains some remarks on why I don't like the Berta ... so head over there and read it. Best wishes in your remodel.
