I am considering to buy a new oven, as the one I have is just awful. The back right and front left corner get so much hotter than the other parts, that the cookies are burnt on one side and still raw on the other. This also leads to quite a lot of deformation (especially all round cookies not exactly in the middle are ovals afterwards).
My new one should absolutely be a convection oven, as I bake more than one sheet at once and will continue doing so - everything else is too much waste of energy in my eyes.
I have read some test reports, but cannot really decide. So far I have lowered my choice to either Neff, Bosch, or AEG. The test reports don't necessarily consider special needs of cookiers, though, so a personal experience report if possible would be highly appreciated
BTW, my current model is a Constructa Energy.
