Look at this KitchenAid wall oven...
It has a steam setting, but you would not know that (they probably don't). Steam has not developed a following amongst manufacturers who don't understand it and the general public who don't want to pay the premium for the feature.
It's a shame. Steam is the healthiest way to cook. Instead of baking out nutrients, you are adding steam to contain them. You can even bake brownies in a steam oven.
The two best products:
Miele...their Masterchef controls prompt you for everything, so it is easy.
Gaggenau...The pioneers of steam cooking. They even have a direct water feed into the oven.
