Initially I'm also considering getting a Medela Freestyle because it's light and compact. Getting from US maybe cheap but the warranty is not covered in sg. Hence if you send pump for service the local will charge you double the service fees (about $200). Taka Baby Fair is now selling @ $799.
Freestyle is a dual pump while Swing is a single pump. Dual pump maybe a better choice because you can pump the milk at the same time hence less time consuming.
Now I'm actually considering buying Ameda Lactaline Dual Pump instead which cost about $300 plus. So far the reviews on this pump are good.
