With my first, I also rented a hospital-grade pump - but due to breastfeeding difficulties was pumping a LOT more than I am now. For my second child (born 5 weeks ago) - I also came to the realization that it's cheaper for me to buy a pump - i got the medela pump in style - and I love it. It doesn't seem much different that the hospital pump I was using 2 1/2 years ago! The lactation consultant at the hospital recommended it the pump in style.
