Got a new Panasonic one with grill and convection and was pretty anxious about the digital interface. But they managed to get it even better. If you ignore the extra options you just rotate the digital wheel that goes in 10s increments up to (I think) 3 minutes and then to higher increments. Then you press "start".

And the grill/convection plus a slightly larger size should allow me to use it instead of a regular oven, at least for my limited needs. Still to be tested.
