I have an Ameda and it works great! I hear Medela is very good too but for some reason was twice the price. And highly recommend a double pump
Having just a single is
If I had to buy it out of pocket, I might have looked at the cheapest... but with the new healthcare laws it looks like I'm covered on electric double pump models with no cost to me.
It also looks like quite a few have used Medela and are happy with it. I've also heard from my friend who gave birth last year that she is happy with her Ameda. So it is a toss between the Ameda Purely Yours and Medela Pump In Style Advanced Starter Kit (no tote)
