I am in the process of doing a kitchen renovation at a second home, and will need a new range. I am limited to using electric -unfortunatelly - and to a 30" slide in model. I have the following questions: 1. Convection oven or not. I have no experience with them. 2. Combination microwave and vent hood. I've heard conflicting opinions. 3. Brand preferences. I would appreciate positive and negative experiences. 4. Any features I can't do without? I have done the Consumer Reports research, but I tend to look at their results with a jaundiced eye. Thanks in advance for your help.
