Breast Pump Recommendations?

chem40

In researching breast pumps, I am leaning towards the Medela Freestyle.  I will be going back to work after the LO comes and plan on pumping during the day.  Has anyone used this model?  Or have a recommendation for a different one?

Also, I know someone asked this question recently, but I can't remember the answer.  What storage bags do you recommend?  

 Thanks!
