With only 22 days left until our new addition arrives it seems like much of my time is spent preparing for the big day. One of the preparations includes purchasing a breast pump. I having every intention of nursing but if for some reason it doesn't work in the traditional way I want to be prepared by having a pump ready to go in my home. I've heard positive reviews about the Ameda Purely Yours breast pump and the Medela Pump In Style. So far the two differences I've seen about the two is that the Medela is readily available at my local Babies 'R Us and Target along with any needed accessories but the Ameda is about $80.00 cheaper and has free shipping! In most other ways they seem very similar so any comments that anyone has about either or both would be greatly appreciated.

I know renting a hospital grade pump is also an option but I'm leaning towards purchasing one of the two. Thanks for your help!
