When I cleaned my Kenmore wall oven first time glass had white steaks all over it.... after repair came and said problem with oven. long story made shorter they are replacing oven with a10% restocking fee (oven is 1 year old) will also have to pay for installation because my contractor did the installation. I'm not sure how long we will be in the house (DH is talking about moving, I'm not... Love my house), he asked me if a convection oven it's better for resale? All other appliances are Kenmore elite, should I upgrade to convection oven now?? Do you think it's better for resale? My kitchen came out beautiful, neighbor who is real estate saleswoman commented how it increased value of my house by 40-50,000 (I did budget update, before appliances cost 13,000. Your suggestions will be appreciated.... oh the glass on the convection oven is darker, so if glass is dirty I don't think it would show as much too.
