As others have said- depends on what you want it for. I have a Medela Advanced dual electric as I work full time and need something that pumps well and quickly- it's expensive but SO worth it!!!!! But if you are only wanting to pump for the occasional time away, you may not want to spend that much. I also had a little hand-held Medela manual/battery for times I needed to pump in the car and it did okay- I never was able to pump as much with it as my big one, but it did what I needed it to. I do have to recommend Medela as a company though. Since I stopped bfing my son 2 years ago, I somehow managed to break a part of my pump. I just now pulled it out to discover this and I called Medela- they sent me a replacement part, completely free (no shipping even), and it got here in 3 days.
