Tom -
The oven in the ad looks like a 27" to me too, but that element looks really odd. All those I've ever seen had the four-pass bake element that is so common to GE. This one looks very different.
About the new ovens - I tried to tell Mom to get just the regular, two self-cleaning ovens model, and I agree with you, that the lower models might suit her better. The two self-cleaining ovens model would have had standard elements, though today concealed elements are growing in popularity. I blame a lot of her dissatisfaction on those concealed elements. The lower oven takes a really long time to heat up, the upper, which is a convection oven too, takes less time. But you're right, it is a shame that something so pricey should be such a disappointment. I think she figured she would not be buying another, in fact this is the only time she ever shopped for an oven I think, as all the rest were supplied with one of the new houses they built.
She still occasionaly talks about how she never bought a Lady Kenmore washer. I think she really wanted one in 1961 when they bought their first washer. The 70 series they had was pretty nice, but she knew she didn't have the best washer. I think she cared about that less in the 70s and 80s, but she still also talks about how we replaced a total BOL 1967 Hotpoint DW with a KDS-17A. That was the only time she had top of the line until these ovens, so she treated herself.
Oh well. If/when they move she can try again. I suggested pulling this unit out and getting a mid line WP or GE, but she doesn't want the kitchen mess and uproar.
I don't like those concealed elements for other reasons - they are not as easy to service. I think some, including Mom's new unit, have to be pulled from the wall to access the element. The last oven Mom had required two elements in its 22-year service with us. About every 11 years one went out. It was about a ten-minute job to fix, in fact the second time all I had to do was go to Sears (the only parts store open on Sunday) and get the element, then install it, and her half-baked pie was back baking before she needed to start on dinner.
I'll tell you one thing that is really funny...the double unit in Denver as I said had a standard oven on the bottom and a self-cleaner on top. This was fine with us as the 1967 HP we left at our last house was not self-cleaning at all. So, we'd use the lower oven for only baking, and the top one for all the splattery roasting, etc. Mom cooks a lot and is a very good cook, and did more of it back then, so the upper oven was cleaned about once every six weeks I'd say, maybe more.
We (I) was told not to do any splattery cooking in the lower oven. One time I put Mrs. Paul's fish fillets in the lower oven, which I liked to use because it got less use than the top. These fillets don't splatter much, but they did a little bit, and boy did she notice!! Too funny - I got scolded and had to clean the racks. Today, that new lower oven, even though it is self-cleaning, is used in exactly the same way, LOL. 1977's habits are apparently still branded in her brain, and the three year old lower oven is totally un-dirtied while the top one gets filthy.
