We are looking at buying a double oven and before I started looking at them, I had thoughts of a double wall oven. I just started looking at them online and see there are double ovens that are more like a free standing stove instead of a wall oven. Wondering if the ranges with the large and small ovens are worth it? What's the deal with the small oven? Are they better than a double wall oven? Is the small oven just for warming or does it do the same job as the larger oven? Any likes/dislikes/"wish I'd done something different"s?
