I lashed out and bought the Medela Freestyle double pump after yet another crummy start to BFing. It's awesome and I wish I'd bought it with DD1 especially knowing how much money I spent on hiring the Symphony with both my girls. Hindsight is a wonderful thing though.

If you can afford it buy a double. Much quicker and more efficient which is very handy when you've already got another LO to watch (and chase!)

I paid around $450 for mine from Babies R Us but I was lucky, mum works there so I got a decent discount. You can get them on eBay though and some places will ship from the States.

Good luck!
