Medela is the best. I had friends w the avent who ending up buying a Medela. Pumping exclusively is hard & often leads to a decrease on supply. Pumps (no matter how good) are not as good as babies are in getting the milk out. I've used thR Pump in style advanced, symphony, & freestyle. The freestyle is the most convienent but the symphony (hospital grade) is the most powerful. Unless you are lucky & have the ability to pump a ton you are going to need a very good double electric pump. Good luck!
