My son has asked me for advice for a range for his kitchen remodeling. He was thinking of a 30 inch, but they do cook a lot, and have some big pots, so I thought a 36 inch would be better for the extra stove top room. We looked at Viking and Wolf at Universal Electric in Santa Clara, and Viking was cheaper (but still expensive!). Should he opt for duel fuel? Is the electric oven really better? Is the self-cleaning feature worth $900.00? Are there some other brands that he should consider? What about reliability?
