I am getting ready to order my pump and am pretty set on the Medela pump in style advanced as I've heard mostly good things here and from friends and family. When looking at the accessories for the PISA, I saw that you can purchase the freemie cups and adaptor kit for $60. Has anyone used them with their PISA? Is iota worth $60 or should I just get a hands free bra? I will be returning full time to work after 12 weeks.
