Check with your ins co, they might provide a medela model for little to no cost. Mine is going to be free.
Medella(not sure if that's how you spell it) they run around $200 but are worth every penny! I've tried the cheaper ones and they don't Las and they don't pump right. You might be able to find a used one cheaper, and the hospital will usually give you the attachments you need for free:)
I got mine off of amazon for $30 or $ 40. I cant remember what its called but I love it. I just searched around for one that had all the stuff i needed and it even came with bottles and evrything. Same quality as Target just cheaper
