i'm still using my ameda lactaline - it has not failed me YET (keeps fingers crossed). having said that, i don't pump that often and if cost is not an issue, then PIS is a great machine (it was S$700+ 2 years ago, not sure about now) - my gfs who use it all swear by it! i understand that it is possible to get relatively good condition ones 2nd hand at about ameda's price range. just ask the lactation consultants at various hospitals.
alternatively, it is cheaper to buy from US (abt 60% of the price here) - you just need a converter and plenty of luck that the one u got is not faulty as the warranty is not valid here.
as for the bottles, you can use the bottles that you pumped in since you will most likely have sterilised the bottles. there are plenty of kits available to 'match' the bottles/pumps.
