Thanks. I guess I am wondering if having a steam oven and a speed oven would be overkill but realize it depends on how one cooks.

Speed ovens are absolutely awesome -- for some types of dishes. So, you certainly can make an argument for a combined microwave and convection oven. But they also aren't particularly cheap. You can buy a no-frills microwave for $100. If you want a speed oven, it'll cost you a ton more. This is perfectly justifiable for your main kitchen. It is a lot less justifiable for an "overflow" space where the microwave will only be used a couple of times a year. For our new kitchen, we are going to get a Miele speed oven. But we opted for the lowest end model, which doesn't have a fancy graphical user interface. That cuts the price in about half, but it still costs about $2k. The reduced user interface also goes along with a small reduction in features (e.g. lack of surround heating). This is not a problem for us, as we will also get a combination steam oven. We expect the latter to be a much more useful appliance overall. So, carladr, if money is not an issue, and you are dead set on needing both a convection oven and a microwave in the same compact unit, then you can't go wrong with a Miele speed oven. If this really isn't ever going to be a main kitchen, then get a cheap $100 microwave an replace it every 10 years (it'll last that long with only occasional use). You can then use the main kitchen for baking.

@Amy Cantu We've been in our house for 6 mo now and I really like the GE Monogram oven. I haven't actually used the speed oven functionality of the speed oven. Just the microwave. And even then, we just use the add 30 sec option. I need to sit down with the manual and experiment with it. Unfortunately, using the speed oven is not as simple as just turning it on. It's pretty complex. I remember when I tried the speed oven at my friend's house it was really hard, and I thought I'd need to dedicate some serious experimentation to getting it to work for me, and doubted that I would ever bother using it as an oven except for Thanksgiving, which hasn't happened yet. My motivation to learn how to use it has been even less than I expected, so I'm sorry to say I can't report back. I also haven't tried using the oven probe functionality for the oven (haven't cooked a roast yet). Need to find the oven probe along with the speed oven manual! But I have done a ton of baking and roasting of vegetables and have been pleased. We were living in a rental house with a viking range and the GE monogram oven is 1000x better than whatever model of viking oven came with the range in the rental. Much more even. I've done two cakes side by side and they came out beautifully without the need to rotate. With a sheet of cookies I notice that sometimes a corner might brown a little quicker than another corner, but not so much that I really need to worry about rotating the pan halfway through. Broiler also works great--I've been making a lot of toast to go with steak tartare and an entire pan filled with toast toast 100% evenly under the broiler--hooray!

I’m in your situation. I’ve been wanting an Advantium forever. Now that it really is time to remodel I’ve done more research. Sadly, I learned there is a required minimum floor-to-bottom of unit clearance that I think makes it impractical to stack with another larger oven. I’m only 5 feet and can’t imagine accessing the top oven in a stack. A salesman steered me toward a Bosch double oven with one of these mysterious speed ovens that you referenced. I am not finding overwhelmingly favorable reviews so it might not matter anyway. Wish I could help but will follow this thread in case someone can aid us both! Good luck!
