How wide are you looking for?

An Advantium can actually do all three things (MW, convection oven, warming), but, obviously, not all at once.

There are 24" and 27" single ovens. They have small interiors, but might be okay. The hard part is finding one that isn't too tall.

Thermador still makes the triple combination, in 27" and 30" wide, which is a microwave, warming drawer and oven in one unit with one control panel. These used to have the warming drawer in the middle, which I think was an advantage, much as I dislike low ovens, but nowadays it's MW on top, WD on bottom and oven in the middle.

"The hard part is finding one that isn't too tall."

That's what I'm looking for too. With everyone wanting double ovens these days you'd think it would be more common. I saw that GE makes one called an over/under oven. Basically its two small ovens in one unit. Not bad, but no turkey the size I cook would ever fit in there! I may still get the Advantium, but have been turned off by all the presets.

Depending on the functionality of what you are looking for - IKEA has 24" microwaves and a 24" true convection oven. It looks like it does a lot for the price. Different styles are offered so there might be a match, might not. They are made by Whirlpool.

Also, Fagor has 24" ovens and if I recall they aren't as tall as others. (I know the 30" is not as tall as others)

To update - the 24" Fagor is taller than I thought. Sorry! FYI

I sympathize with you because I have wanted a double oven for YEARS but we wanted to be able to keep a microwave above it to avoid remodeling other areas of the kitchen. In fact, I had a post looking for a similar item about a week ago. I can tell you that in all my looking the only item I found that would work if you want the width of a normal oven but not the height (unless you can go with a 36 inch oven) is the GE single/double oven. GE does claim that you can cook a 23 lb turkey in the larger oven, and the few reviews of have seen are positive. Perhaps you could find out exactly what the interior height is of the larger section to see if the turkey claim is accurate. A Miele dealer tried to sell me on the idea of the speed oven, but while it seems like a great item, I really wanted a second oven wide enough to accommodate a half sheet pan. I also looked at the Advantium, but didn't need/want all the bells/whistles with that. I personally like having a microwave be just a microwave. I actually had just about decided to get the GE "2 in 1" oven to use until we were ready to do a more major remodel (perhaps in 5 - 10 years) when my husband shocked me by saying 2 days ago that he is willing to make some modifications to an upper cabinet and move the microwave there. It will mean we have to get a very small microwave, but I don't use mine for much besides popcorn, heating frozen meals, reheating, etc. We are actually going to get the Wolf L series double with a warming drawer under it, which I have dreamed of while I have used a single Whirlpool for the last 17 years. Much good luck as I so understand your problem. Perhaps you could do a post re the GE oven and whether people are happy, have been able to cook large turkeys, etc.

Kayl,

The bagel defrost setting works amazingly well on the Advantium, but I generally ignore the presets. You really don't need to use them, though there are some things that you have to page through menus to do. I think they're mostly there so that you pay attention to which function you're choosing and which tray you have inside.

You really can choose your duration time and power, or the convection oven temperature, and use it in a conventional manner. Yes, the controls can be a little annoying, but once I discovered that one could get find adjustments in microwave mode by turning the knob, I was fine with it. To just zap something quickly you can press express, it turns on right away with 30 seconds on the duration, and you can change that to 10 seconds or whatever you want by turning the knob.

Just saying, if you think the Advantium (or Miele speed oven) will serve your purpose, it's worth taking some food and pans to the showroom and trying out the different modes and how to access them. Read the manual first, however, because a lot of the sales reps don't know how to use it. There was one at the store where I bought mine who didn't even know it did more than microwave! They used it for popcorn so that's what she thought it did!

Were you trying to get the full sized oven, short oven, microwave and warming drawer all in one stack? I wouldn't do it. That will make them all inconvenient. At that point I'd look seriously at one of the combo units, and get either a countertop MW or oven. A lot of people love the Breville "toaster oven" as a second small oven. If you don't use it all the time, you could also hide it in a pantry and only bring it out when you need it. My mother has a roaster oven she puts on her dryer when she needs extra oven space. Otherwise, it lives in storage.
