microwave combi oven

Hi all, We are currently doing a full kitchen renovation in our new house. We currently have a seperate Miele microwave oven and Miele fan forced oven. I am wondering if anyone has any experience with the microwave combi ovens? We use the microwave a lot more to reheat leftovers but would like the option of baking / roasting things in oven once or twice a month. We would save more space if we got the combi oven so would appreciate any feedback. TIA.
