Correct me if I'm wrong - but I am not a fan of buying their warranties because most everything is already covered. It's not like if you don't buy you aren't going to have a warranty.
I like Sears, Lowes, or Home Depot. We have a lot of Kenmore appliances and Whirlpool. I don't think you can go wrong with either of those. You just have to look for what you can live with. If you have a large platter that you would LIKE to put in your fridge but can't now measure it and see if it fits in one at the store. I will NEVER have a side by side again - even the offset ones, though that does help!!!
Too many bells and whistles are just more bells and whistles to malfunction (some of them anyway - not necessarily all of them). You'll do fine ITK - you want me to keep the X out of your fridge??? I'll be glad to!!!!!!!!!! Mine doesn't get in the fridge he just comes in and uses my child to break doors (now THAT went over well).
