which is the best breast pump and why? looking for opinions so I know which ones to look at.

I love my spectra. I tried and reviewed 8 pumps and spectra is my favorite http://allaboutbabysworld.com/?s=Breast+pumps

Both of my sister in laws used it and loved it. Now I'm just trying to decide if I want to go with the basic package or upgrade to the backpack style lol

That's what I was thinking to cause its been number 1 on all the things I've looked up

I haven't personally used one yet, but in my research I've not heard anything bad about the medella. It's the one I am going to get!
