I have Neff ovens which are great, but they are all built in. If you are looking for a free standing oven. I used to own a Panasonic flatbed combi oven which had no turntable so was great for using as a standard oven. Not sure if you are mistaking the bit about heating from above as the microwave/grill rather than the full co bias I am sure that quite a few full combi microwaves will have proper heated oven/grill/microwave and are useful for using as a second traditional oven.
What I would suggest is going on some manufacturers websites and looking at all the different models which will give you a good idea.
For me the Panasonic is a good choice for a freestanding oven or if you are looking at built in,the Neff is great but not cheap at around £1200.
