This topic has kept me up at nights. Like you, I hate using a big oven when a smaller one will do. So, I have decided on a speed oven--likely Miele, although GE and Electrolux makes them also--which is a microwave, convection oven, and I think/hope it toasts as well. They are a little less than a half-oven. I would go for the wall oven, warming drawer, and toaster oven/speed oven for you, and skip the double ovens. I think double ovens are great if you bake in large quantities where the food needs to be precisely cooked at different temperatures, but for meats and potatoes and such, the temperature differential is not really a big deal. It is easy to reduce/increase both the temperature and time and still have everything come out fine. A warming drawer is fantastic. Remember, with a convection oven, things cook faster, so for that occasional large meal, it is easy to cook many things and as they finish, put them in the warming drawer while you go onto the next item. Also, with 6 people in your house, you will have kids coming and going at all hours of the day. Rather than say, "Honey, let me heat up dinner for you," you can relax on the couch with a glass of wine and say, "Honey, your dinner is in the warming oven."

toaster oven. it's more versatile. It can top brown bagels and english muffins. It can reheat food. Toast may be a bit less evenly done, but overall more utility.

We rarely have a need for a microwave, but after doing without for three years I knew I wanted one. We opted for the Bosch speed oven, and use it much more than I thought I would. Use is about 30% speed cooking, 20% microwave, and 50% of the time we use it as a small convection oven. However, the oven that has fully won me over is the steam oven. It is wonderful, and after some glitches with the control board it is working flawlessly (Bosch has been top notch for repair and service). It does everything that a regular microwave does except pop corn. Food reheated in a steam oven doesn't even compare to food reheated in a microwave. I've used all three (speed, steam, full size convection) at the same time on quite a few occasions and love having them all. However, if I had to pick just one of the smaller ones to go with my full size it would be the steam. I'd put a tiny microwave in the pantry for that rare need. Good luck with your new ovens!

We have the full size Breville toaster oven bought for the kitchen reno and the Bosch speed oven. I really couldn't live without either now. I guess you could toast bread on broil in the speed oven but that mean you would have to get the rack out and it's just not as convenient or time saving. Having the versatility of both ovens makes me happy. We also have the side opening Bosch oven which is the star of the kitchen regarding how awesome the food comes out of it and ease of use.
