Breast pump recommendations?

Danielle

I know it's still a bit early, but I want to start considering my options. I'm a first time mom and I'll probably be pumping at work at least once per day (but probably more) depending on childcare arrangements. The pumps I'm currently looking at are the Lanisoh Smartpump, Medela Pump in Style Advanced, and Spectra S2. Which of these do you like the best and why? The pump will be covered by my insurance so cost isn't an issue. Thanks!
