Hi A.,
I pumped for several months after my daughter was born because she had major problems latching on that no one seemed able to solve. Anyway, the lactation consultants strongly recommended renting a commercial pump (you can usually rent from a local hospital) for anyone pumping full time. They told me it was just easier and faster to use. I never tried anything but, so I can't give you a comparison, but if you have trouble,you might want to consider that.
Good luck!
