I used the Medela electric for my DS. It was good if I was BFing as well but as soon as that slowed it wasn't great at getting milk out.

I've bought a freestyle for this one, $480 on eBay, I have yet to try it out but did lend it to a friend of mine who has said it was brilliant so I'm looking forward to using it. I'll be back at work after 4 months so need something portable.

Good luck!
