In my old house I had a Maytag Gemini with the double oven and smooth cook top. I loved it. I have a GE in this house and so far I have not had any issues with it. I don't really know how old it is since it was in the house when we bought it. I think you can have lemon appliances just like you can have a vehicle. When it comes time to replace this range I will be in the market for another one with the double oven.
Look at different ones and read the reviews that other customers have posted as well as those from publications such as Consumer Reports. This will give you a good idea about the reliablility.
