I have been thinking of getting inverter one which could control actual power level instead of doing on/off cycle of maximum power. But the probably cheap one that was left in place as slightly annoying to remove(power cable behind shelve) just haven't gotten around to. I got also top of the line Samsung one with all the features(convection+grill) stored but it was worse as microwave than the cheap one... Can't get that, I buy essentially best model and it does not do main job properly...
