We have the Panasonic convection microwave and the Breville convection toaster oven. Our main oven is a GE Monogram convection oven. 1. The Breville toaster oven is the best toaster oven we've ever owned. During Christmas visits my adult children dubbed it the magic oven. It toasts bagels perfectly because toaster settings can be customized. It bakes frozen pizza well enough that it can be considered more than barely edible in a pinch. It crisps homemade pizza to perfection. I have convection roasted game hens in it and cooked tuna to medium rare in minutes after searing it's edges on my cooktop. Overall it's one of the best small appliances I've ever owned. 2. The Panasonic does all of the above, has a larger capacity EXCEPT it is not a toaster. We toast a lot of things that wouldn't fit in a regular slotted toaster so toaster ovens are a must for us. We live in Florida so we don't need two full size ovens. We also (contrary to most people, it seems) use a microwave oven as a full partner in our array of cooking appliances. (I don't know if it is still available but the Microwave Gourmet cookbook by Barbara Kafka is a great resource for fully utilizing a microwave oven. She has such great recipes that I often adapt the seasonings for use in a regular oven also). Thus, we are happy to have the Panasonic with the dual use capability. Although we did our installation several years ago and I can't remember what we paid, I'm sure the $200 price quote for a Panasonic trimkit is way too much. You should check on line to try to get a better deal. HTH.

We have the "V2" version combo wall-oven and microwave (JMW3430), installed a bit over a month ago. We really like it so far, although we haven't begun to use many of the features. The main oven has a dual-fan convection system, and the upper microwave can also be used as a convection oven, as it has a heating element besides the microwave. We thought about getting separate units, instead of a combo, but the slightly lesser total height of the combo unit allowed us to fit a warming drawer underneath. I'm not too worried about the "need to replace the whole thing" issue, as I'm usually more inclined to repair something instead of replace. It seems to me that the Whirlpool units have fewer features, but that the corresponding KitchenAid models are not that different. (Our prior unit was a Whirlpool combo oven/microwave, that lasted roughly 19 years, although it did need a controller board replacement at one point, maybe 7 or 8 years ago.) My other possible concern for the long term is whether the color LCD display and touch-screen will last. No reason to suspect trouble, though. The "culinary center" and sensor-based cooking capabilities of this unit are very cool, even if not really necessary. And this last is completely frivolous, but the ability to select from a bunch of different color scenes for the main display background is kind of cool.... We also got a free-standing french door (4-door type) Jenn-Air fridge, a "free" Jenn-Air dishwasher as part of the package, plus the above-mentioned warming drawer. The dishwasher is very quiet, although like all new water-saving dishwashers, it takes a long time to run through the complete cycle. My feeling on both the fridge and the dishwasher is that they are basically gussied-up Kitchenaid, and I've always felt that Kitchenaid was pretty good at both fridges and dishwashers. (As an aside, I am loving the extra door/drawer, which in this case is a refrigerator drawer above the main freezer.) We went with Dacor for our cooktop, just because we liked some of its features a bit more than the Jenn-Air cooktops we were looking at.

I wondered about the same thing before I got the 240V Advantium. But after using it for almost a year now, I think the 950W is enough. One of the things I noticed about the oven is that it has a very good sensor in it. I can just select the reheat plate of food feature, for example, and the MW will just stop on its own. It has been very accurate each time. It does the same for popcorn. There are also some items that required more MW wattage for the browning plate or packaging to work, like frozen burritos, pizzas, pockets, pasty and the like. These items come out better in the speedoven without the browning material. I don't miss the extra wattage.

As far as I know, yes. I don't have experience with these, but reading a lot on GW I would suggest looking into MW drawers that can be mounted under the cabinet as well as putting a standard MW in the upper cabinet either behind full doors with shelving above or in a separate compartment with lift up door. You can search GW via google to read about them more. I don't know enough about speed/steam options to know if there are any that might work in those configurations, but I'm sure someone here will!
