LO will be arriving in less than 3 weeks (eek!) and I'm pretty committed to the idea of breastfeeding. Many have said it's best to rent a hospital pump first and then purchase your own pump, but I'm wondering if this is cost effective or makes sense for someone who knows they will be breastfeeding?

How much did you pay to rent a pump, and if you could do it over again, would you have rented or just bought a pump in the beginning? Thanks!
