"Speed oven" micro/convection combo

We're finally remodeling our eichler kitchen (last remodel = 1984)! Instead of a double wall oven, we're looking at a single wall oven that is conventional/convection, and a "speed oven" microwave/convection combination.

Has anyone had any experience with the so called speed oven (electrolux, for one) and the concept of microwave/convection combo (I gather it's either/or!)?

many thanks, and merry christmas!
