First off Sattie, I'm going to go into the appliance store (dedicated, not a box store) and see just how much this is going to cost as opposed to a projected savings. I'm going to stick with the upright, that I know.
On a sidenote, I had a side-by-side fridge for years and loved it. Whether it's a freezer item or a refrigerator item, you had eye level and you had bottom shelf. I think that's been my biggest problem with my new fridge, other than four repairs in seven years.... I just plain don't like it.
