Working: Infant, The First Years

Is First Years or Evenflo Breast Pumps Any Good?

When my son and daughter were born premature, the WIC offices where I lived provided a motorized Medella pump supplied from a medical supply store. Obviously this was very good. I know that Medellas are sold in Target but I also seen other brands. Is there an "off" brand ie, Evenflo, First Years, etc. that is comparable but without the price??
