I am done with my Medela Pump in Style Advanced. I bought it in December 2008 and used it for five months. It is in excellent shape and I can send pictures if you want.
In addition to everything that comes with it, I also have a mesh bag for hanging dry pump parts, an extra pair of collection bottles (I found it really helpful to have two to swap back and forth), and a Medela BPA-free slow flow bottle.
I am also selling breast shields in another thread, and if you buy the pump I will include a pair of these shields, whichever one you want.
I am asking $150 plus shipping.
PM me please if interested.
