I have done a lil bit of research on breast pump. Medela is considered the best. Some ppl say that ameda is comparable to medela but at a much lower price. And if you want a cheap 1st hand medela, buy the US set from blog shops but you need to buy the voltage converter (which can be bought at like $10) if not, there is a lot of sales going on now, so you might want to hunt for really cheap bargains. For the breast pumps now. But I still think that breast pumps are so expensive.
And on a side note. Anybody interested in buying Ipad 2? I can get discounts.
