Other side of kitchen . . .

If that is a 27" oven you may have to look for older stock, sears outlet, or craigslist to get something that is not too expensive and will fit. Most ovens are 30" now. I think it is ok to have a stainless oven since your WD has stainless trim right beside it.
Sears outlet or other retail is nice since you can purchase the installation also, those ovens are often hardwired into the 220V supply. If you buy an older oven off craigslist you may be able to sell it for almost the same price next year. White appliances sell very cheaply now.

I don't see much room for a countertop temporary convection oven which I might be tempted to use, rather than replacing the oven, if I was planning a definite remodel in a year.

Scrappy25, actually it is a 30" so I can get a new one, but I have thought the same thing about doing a countertop where the toaster is. Just know how disruptive redo's are and might want to go ahead and get something that can be moved so I can do a turkey!

I would go ahead and get the oven you want, then add the MW when you remodel or the MW dies.
Only input I can give you on brands is DS owed a KA oven/MW unit and the MW door had to be repair twice, plus it had another problem I can't remember. Also, both units were not user friendly when it came to programing. I do know that after using (or trying to use) the MW, and attempting to set the timer on the oven, that I never wanted to own one!
My Dacor wall oven is 11 years old and I can't say enough good things about it!

What is the point of a wall oven if it is almost as low as an oven in a range?

I feel your pain. :) I have not used my oven in years. It is a huge old GE gas oven and it heats my house so badly in the summer that the old air conditioning cannot keep up. And I swear I can smell gas fumes. I have a detector, and have had it checked out and apparently it is fine but I'm still leery of it so I just don't use it. Instead I have a Breville countertop smart oven, which I love and since I only cook for two it is adequate. I will eventually remodel and get a new oven but until I do the smart oven allows me to bake, broil, and toast (got rid of the toaster due to lack of space).

First, if you haven't used it since February you might survive, get a Breville till then and use the oven for storage :) Buy a cooked turkey (I'm getting mine from a local restaurant since we are eating early!).

However, if you are set on an oven: Is it gas? If so, stop reading now. If not, here's our story: a new oven needed a new 40-amp line, and our old one had no electronics so it didn't have the cooling fan. Do a search on the appliance forum for "quiet oven" or "noisy oven"; the cooling fans can be seriously loud.

Renovator 8, we are finishing a kitchen remodel and I have placed my wall oven at the same height as Kelrobin's. We don't use our oven very often any more because we are empty nesters. We have installed a speedcook oven just above it that we plan on using several times a day. Because I am so short, we needed to put it at a height that I could easily get in and out of since it has a drop down door and not a side opening door. That means the oven that I get into only a couple of times a month, if that, has to be low. So sometimes there are very valid reasons for such choices.

Kelrobin, I think you should just get the oven that you want. Consumer reports rates Whirlpool, Maytag, KitchenAid, and Bosch all very highly. We just
went with the white glass front JennAir that looks similar to yours. I am wondering why you are switching to stainless when stainless seems so much harder to keep clean?
