If price is not an issue, do choose an Aprica, considering that you will need a "one-hand" closure system that stands upright when closed. One hand closure system is important to you because you need to be able to shut your pram with one hand and the other holding your baby when you go up / down the escalators at MRT stations or when boarding MRT trains or buses.
It is the lightest in the market. The good features of an Aprica is patented, thought you should know. You pay for good quality. It is known to be the Rolls Royce for light weight prams! You will not regret it. Robinsons at Centre Point has the largest range of Aprica's.
The one down from Aprica would either be Combi or Lucky Baby.
