I have been looking up pumps, as I plan to BF and I would like to pump as well. I am completley confused as what to get. I get that a dual electric is the BEST way to go, but they are expensive. (yet cheaper to buy then continue to rent). What ar eyour thoguhts on All the different types of pumps. Manual? Electric? single? dual? Preferred brands? Any tips or advice / reviews you have would be great.
