Why the cost difference between the built-in and OTR advantium?
I currently have a microwave built in to the cabinet above my single wall oven. I'm contemplating replacing the microwave with an advantium, but I'm confused why the OTR versions cost about half what the built-in versions do. What is the difference between these that leads to the cost difference? I see that the door swing is different (side to side for the OTR version and like a mini oven door in the built-in version) but is that the only difference between them? What am I missing?
