I had also planned to BF, and bought some Avent bottles & a microwave steriliser in case. I then had trouble BF'ing, and hired a medela pump to use (as this is what my hossie had used). Didn't realise... the medela bottles can't be microwaved, so my microwave steriliser was a big fat waste of money... something to watch out for! If I had my time again I'd just get the more expensive steriliser (electric) or... wait and see what i needed - you can always boil stuff on the stovetop.
