We are looking at buying two AEG wall ovens, with one of them being a regular 30" (most likely), and the other being a steam oven.

As another poster has recently mentioned, it seems as though people often do most of their cooking in the combi oven.

We are a family of 5 and do a lot of cooking at home. Any recommendations on whether to go for the full size (74 litre), or half size (31 litre) for the steam oven. Trying to balance efficiency and energy use, with practicality!?!?

Thanks!
