The speed oven is no harder to clean than say a Dacor or Wolf convection/micro oven. Is it lower powered? Maybe, but compared to what? Does it still do chicken nuggets in 2 min.? Yes. Re-heat the leftover casserole? Yep. Will a unit with 1200 watts do it quicker? Yep. So if 25 seconds will make or break your day then you'd better pass on the Miele. Don't get in a pissin match with people over specs. That's a common play for sales weasels to engage in when they can't talk about quality, service, reputation, innovation, track record. ect... 4500 is a good deal for both those units new.

If you are having an installition tech do the install, he will undoubtedly, cut out the back of the cabinet. I installed into a 27" standard oven cabinet. and so I had close tolerances and careful front surgery to do on the cabinet. Installing into the larger cabinet should be easier for your tech. I was doing the install myself, and when I encountered the depth issue, I called a carpenter friend that does a lot of kitchen installs. I asked him how often he has this kind of problem and what he does about it. He told me that it happens about half the time, and he just starts cutting the back until he gets enough space. If cutting the back panel isn't enough, he said that he just "starts hacking the drywall away" until he gets enough space. I had enough depth after I cut a sizeable piece out of the back panel. It amazes me that the appliance manuf. don't design to the standard cabinet size spec, and don't warn you that this could happen. I had a real sinking feeling, when I first realized that it was not going to fit into the cabinet. It turns out that cutting the back panel does not compromize the structural integrity of the cabinet. BTW, I installed into Thomasville cabinets. But I did check other brands of cabinets, and it was going to be a problem in all of them. If you were concerned about oven size, why didn't you get a 30" oven? That is monstous inside. I could not fit a 30" cabinet in, but I would have preferred to have the 30". Goodluck Carguy

Here are the interior dimensions (W x D x H) for my H4082BM: 18" x 15.5" x 8.25" Because the upper broiling element intrudes into that height space, the highest usable vertical height is 7.5" (from oven bottom) or ~7" (on the glass tray), or less. Certainly no problem for a 9" x 13" casserole dish.

I have a few questions: -Can you fit 9 x 13 pans in the smaller oven? 12 hole muffin tins? -If they do fit in the smaller oven, are you happy with the way they bake? I've read extensive reviews on here, and one person mentions having to shuffle their sheets of cookies and biscuits around in the larger oven in order to get them to brown evenly. Have you found this to be the case? -How long does it take each oven to get up to temperature? Thanks for any help you can offer! : )
