I too used the Ameda purely yours breast pump. I bought it used on ebay. I did a lot of research. Many places said not to use a used breast pump. But some sites said it was fine, as long as you got new tubes...that is one reason I used an Ameda because the sites I read said that the tubes were the only place that the milk touches, so using a used one was fine. Also, our insurance reimbursed us $50.00 for buying a breast pump. Check to see if yours does the same.
I did not use the Ameda bottles. I used Pump-Mate Breast Milk Storage & Feeding Kit. They are hard to find...I got them new on ebay. I did a lot of research about storing and freezing breast milk. The pump mate breast milk storage kit comes with disposable little bags that you store your milk in. I liked their bags because they are shaped like bottles and were easier to use.
Also, some of the research says that each time you transfer breast milk from one container to another, you lose some of the nutrients. So, it is best to pump it into the same container that you will use for feeding the baby.
Good luck with your choice.
