Agree with PP's that the Ameda Purely Yours IS OK to buy used. but you will need to buy new tubes/hoses and caps and the things that look like a silicone shot glass. They market this as a Hygeine Kit. I bought one on Ebay for a much lower price than the only local store that carried them.

The Ameda Purely Yours is called a "closed" system in that the milk never comes in contact with the pump itself.

I would ask how often or for how long it was used, etc. Mine was pretty noisy but I got used to it.

I did have the tote with the cooler in it. The tote was actually really nice. I wish I could find a purse that shape and with straps like that! I LOVED the cooler bag because it was the perfect size so bottles did not tip over and it had freezer packs that fit in to all the sides, so it stayed REALLY cool. But you don't NEED a tote.
