Can't decide which oven to go for. Looking at getting a pyrolitic Miele or Neff oven. Drawn to the Miele because everyone goes on about how good they are but I'm put off by the oven only coming with one shelf. However, my current oven only has one shelf and that hasn't been too much of an issue. Also, where do you put the other shelf when you need to put something big in the oven? Also like the fact that the Neff oven has a sliding door. What are your views? TIA
