there are varieties in pumps. i heard from my colleague that there will be another big scale baby fair in April. if you are going down to the fair, u can go down to the booth and take a look at the different pumps, have a feel of how it is, wherethe is it easy to handle. Like for myself, I want something that is convenient for me to pump on the go, that means i dont need to be stuck at at a certain place just to pump milk. The Spectra M1 is one of the models that i'm looking at cos my colleague is using it and I saw how convenient it is. She just put into her sweater and she can walk around the office while pumping milk.
Also, please buy a double pump cos you don't want to be pumping one side and when the "let-down" effect comes, the other side will start to drip. Cos sometimes Medela might work for someone else, and it doesn't work for you. it depends on the suction and also if the pump is able to let you totally empty out both breasts when pumping.
