Trying to decide on appliances for a new kitchen, and read a few people saying the top ovens of their double ovens are not that great. We rarely used ours when we had one and I suppose yes, didn't find it great. So contemplating having two full ovens on top of each other. Does anyone have any feedback on that set up and has anyone done it with DIY kitchens units - if so which one (we're looking at the taller units that they do, not the 1970)?
