Hi HowardF,
We appreciate it that you are considering a Samsung home appliance for your kitchen.
Currently, we have 2 built-in microwaves that you may consider. I have shared the Samsung links below for your reference.

Since you are looking into getting a wall oven and a built-in microwave, we suggest looking into our combination wall oven where the top is a microwave and the bottom is an oven. I have shared the link below for your reference.
