I've a Neff circotherm oven with pyroclean function. It's fantastic. With the Circotherm you can cook meat, fish & sweet dishes at the same time and one won't end up tasting of the other! There's also a pizza setting, grill settings, & thermo grilling which is brilliant for roast potatoes. Cleaning is a doddle, switch on the Pyroclean and wipe out the dust a couple of hours later.
I also have a Neff combination oven and microwave and am really happy with it, it has various grill & hot air combinations and can also be used as an oven and microwave at the same time.
When making things like lasagne I notice that they brown evenly whereas with my old oven I used to have to rotate dishes.
Also, if you buy a Neff appliance you can attend one of their demonstrations (think only in Dublin though) where they show you how to get the best out of your oven.
