I bought a cheap one of ebay....its was electric and a brand name I had no idea of...but **** it saved my hands from pumping away for hours and it was small enough to take in my handbag..adaptor and all (it came to the mercy hospital with me) - I paid $30 including postage for it....will try and find it and PM you the details.

i highly recommend the tomme tippee bottles...chemist warehouse has them for $16 for 2 and the teats are $7. No trouble what so ever between nipple and teat...we had the same concerns as you did. We had Advent bottles and Mateauz hated them so we bought the tt ones.
