I recommend the Medela Freestyle.
You can get it online at http://www.addalittlelove.com/ (around $275)
I love how small and portable it is. The pump itself is about a pound vs. the 5+ that the others are.
The bag it comes with doesn?t scream ?breast pump?, and the pump itself can fit into a purse if you want to.
I LOVE the ?let down? button and the easy adjusting on the pump, no dials to adjust separately.
It?s strong too! I used the Lactina hospital pump and I thought the Freestyle was better!
It?s hands-free (not that big of a deal, you can use any pumping bra or this trick http://www.kellymom.com/bf/pumping/hands-free-pumping.html ) but being able to move around with the pump was a plus!
It uses a rechargeable battery, and I only have to charge it once every 7-10 days.
Like any Medela pump, you can pump into the $1 Gerber bottles and can use any size flanges.
