Which brand of bottles to purchase?

I plan to breastfeed with a fairly quick transition to pumping and feeding.  I would like to purchase bottles that are best for breastfeeding mothers, just in case I choose to do both (work schedule calls for pumping and feeding at times). Does anyone have any recommendations? Thanks in advance :)
