My research from appliance repair techs indicates a real problem with the ice makers on the bottom freezer french door refrigerators. Especially Samsung and LG. Thinking of going side by side built in. Need the frig space of a deeper frig so would have to go to a 42" or 48" total width in order to get enough frig cubic ft. Any thoughts on the subject. Who has the best built in product for the money? Sub Zero, GE, Kitchen Aid, Thermodor, etal. Are they worth the extra $.
