Funny I had some of the same constraints. I have a 30" Wolf cooktop and like it very much. I am now used to it, but 2 years ago when I did my kitchen, I went from a 30" range to the 30" cooktop, it did at the time feel a bit compacted to me because the range had the controls in the front vs. the top as on the cooktop. I am now used to it and while your "big" my not be my big, I don't have any problems using wide pans simultaneously on my cooktop. To make risotto for instance, I use two wide (9 -10") pans on two burners back to front and don't have any problems with the space. 10" is my widest pan however. Surface wise it hasn't felt tight to me. However, there are 2 cooks in the family and it felt a bit close to me in the beginning going from the 30" range to the 30" cooktop but now it is not an issue. I do love the cooktop, though. Performance-wise it is very good. If the latter consideration is relevant to you, however, you may also want to take a look at the Viking designer series - the cooking surface spans the 30" width, controls in front. Do study its outputs though - for me, the high at 14KBTU may have been fine although I preferred the 15KBTU, but 2 years ago, the low was 1.2KBTU and that was too high for the things I do want to be able to make some times. At 675-700btu simmer settings for the viking now, that is a LOT better. The Wolf has 300 or 400btu lows and I find that I use them quite a bit so I would not have been happy with 1100btu for a low. I have a Bosch oven and like it very much indeed. I have a 30" 700 series but since Bosch came out with new models this year, I don't claim to know anything about them. The 700series is a relatively basic oven even though it was their top offering 2 years ago - bake, convection bake, convect. roast, broil, convect. broil and warm, thaw, dehydrate or some modes like that. It is self-cleaning although I've only ever used it once. Goes down to 100degrees in "warm", 120degrees in "dehydrate", 170degs in the cooking modes. The direction of the heat source distinguishes the modes. It does an excellent job with temperature control (+/- 7 or 9degrees per my experience except for when you open the door in which case the temp can drop sizeably depending on mode; Miele Wolf and Gaggenau are even more precise & hold temperatures to within 5-7degrees), very even whether in bake, broil or roast; I liked its size as it was a smaller oven. I LOVE its interface. I noticed Consumer Reports doesn't like it either but haven't been able to figure the reviews out. I will say that you do have to experiment a bit to get used to how to cook in it - either it is the convection or the Bosch itself but there are things I have had to consciously start to do to ensure good performance; I did have some corkers in the beginning before I cottoned on to that. Placing the rack too close to the front of the oven instead of in the center or towards the back will interrupt its' air circulation (in convection) and the net result can be a asymmetric cooking. Likewise sorting out how to load the racks for multi-rack cooking so that they are evenly spaced out else same story. That sort of stuff. Anyhow, I like my Bosch oven very much but claim no knowledge of even any of their new models. I absolutely love the cooktop, but I think that the oven maybe what I play with even more than the cooktop.

On AJ Madison for example, the steam only oven DG 6500 is at 2.5k, while the combi steam DGC 6500 XL will cost more at 3.5k. I have a 6805 myself, and can vouch that it is worth getting a Miele combi. With broiler, top and bottom heating element, ability to control humidity level finely, drain, and waste reservoir, and perhaps a few more features, it makes the oven more complete and for most of small family cooking, it will be your main oven.

Try this please.

Cleaning is pretty easy, as long as you don't expect the oven to ever look factory new. My oven cavity has a couple of minor but permanent stains. Doesn't bother me at all, but I just want to make sure to set the right expectations. As for plumbed vs non-plumbed, we deliberately chose the plumbed model and we are very happy with this choice. It makes it so much more likely that I'll add steam every single time, rather than skipping it, because I am too lazy to refill the water. Also, it allows me to cook things that take a long time. The CSO has very precise temperature control and thus makes for a very convenient alternative to an immersion boiler for sous vide cooking. But that can take many hours of cook time, and with a water container you have to worry about refilling ti. I do understand the concern about water leaks though. Realistically, it's no different from ice makers, dishwashers, and other appliances. These don't fail frequently, but they do occasionally spring leaks. And that's why we put a drain pan underneath the CSO. It drains into the same pipe that the oven drains into. Hopefully, we'll never need that feature. But it does give me peace of mind, and my contractor didn't think it was all that difficult to add into our cabinet.
