I've used both medela and ameda and I much preffered the medela. It is an Awesome pump. I'd recommend the pump in style. I'm going with medela this time around, but only a single electric as I'm a sahm and will be mostly bf'ing at home.
edit: I've not thought about insurance, I wonder if mine will cover the breastpump. I'm going to find out. If so, I'll go with Medela pump in style! My concern was cost, and since I'd be at home anyway I wouldn't need a fancy double pump, but when I was working and pumping I couldn't imagine the time it would take to do them one at a time.
