I always had a double oven and rarely used the small one however in the last two houses - rather kitchens I have remodelled, I have had a European convection/microwave (no turntable) installed.
I now rarely use the large oven, and particularly as my Neff small one has pyrolitic cleaning and I just turn it on and it cleans itself like new!
I would never buy that double oven again after having worked with this type as they are quite large for two people and fit a few dishes in at a time and you can do micro/convection together which is great.
so, I DO have two ovens, but one is a combination of microwave and oven.
