Have you gone to look at any of these in person to see if you like them or not, to me that is the biggest thing to do. I loved the look of one model but hated how the racks and doors felt and after that wouldn't consider it even if it was the best rated product on the market. I personally am considering the 30" version in a single wall oven for the Electrolux and love the look and feel, though I am putting that up against a Wolf as to which we will end up buying to be honest.

I have had the Kitchen Aid KEMS308S for 5 years. I had not noticed that the microwave power was low. I doubt that power will be an issue. I assume that many ovens have cool down features. They are not running when the door is open. It is ture that the fan makes some noise, but it isn't that noticable. When I originally purchased this oven I had been intending to get individual ovens, but it turned out that the individual ovens had been discontinued. I see no difference between your choices because they are all double ovens and when one fails, they both fail wheras individual ovens could be replaced individually. I have not heard of the microwave section showing a high rate of failure. You didn't even mention the advantage of the micro/convection. It is not just a microwave, but a real convection oven with a broiling (sort of) element. It is not a speed oven because it does not microwave and heat at the same time. Actually it CAN microwave and crisp via the broil element. Anyway it is a small second oven that can bake a pie or bread (or a small trey of cookies I suppose). It heats far faster than the regular large convection oven because it is small. I find it very useful. The only problem is it is occasionally in use when I would want to reheat a cup of coffee etc. I keep an old microwave in the garage for those cases. While I hope I have relieved your concerns, I believe that there IS an issue. I have had no problem with my oven, and it has been several years since the Main contingent of problems: similar models have encountered a higher than normal thermal fuse blowing during the large oven self cleaning cycle. Unfortunately, the fuse is located on the back of the oven and is a $50 item and shuts everything down. Of course, most people see no problem (myself included) and the problem is certainly due to excessive heat behind the cabinet that could probably relieved by making sure that there is a little more open space back there since you are still installing cabinets? In any case, this is probably a general issue. Other ovens have failed on self clean cycles. At this point, many people concider the self clean to be a marketing ploy and don't use it. Perhaps we just don't make enough spattering roasts, but I have easily wiped down the main oven. It wasn't stuck on hard. Perhaps the surface has anti stick coating? My self cleans have been done mainly to test the thermal fuse problem. By the way, the microwave interior is stainless steel and IS much harder to clean. In fact, that last sentence is probably my most important piece of information. I imagine it would apply to other convection microwaves.

These are the exact 2 ovens I have narrowed it down to! I've heard that Thermador has fixed its old oven problems (missing insulation) -- but I am still a bit wary and it is more expensive. On the other hand, I love the look of the Kitchenaid KBES209BSS, but I have seen people posting reports that there is a long pre-heat time and loud fan. My current GE Profile oven (which just died) takes a while to heat, and the fan is fairly loud, so I am wondering if the Kitchenaid is about the same -- which would be acceptable. I really like the look of the Electrolux, but was warned off them because of poor customer service. Did you get any of these? And what do you think so far?

The KA broiler is worthless IMO - the door must be closed when broiling, and the entire oven heats up and the food winds up tasting like it was baked in the oven rather than just having its top seared. The ELux allows the door to be opened properly to the first notch when broiling allowing for proper grilling effect, or at least did the last time I looked at them. Also the fans in the KA are noisy.
