Heyy -
We are using a Capella stroller. Reasons to buy this one was the weight (5.5 kg), the price (+/- HKD 640) and that is was suitable for newborn. We are living on HK Island and I am using a lot the public transport, therefor we are happy with the Capella, it is fairly easy to handle. One thing to consider: this stroller is built for small people, great for me, but a little bit uncomfortable for my husband ;-).
You can buy it in WING ON and a small shop in 38, Eastern Street, G/F, in Sai Ying Poon, close to Tsan Yuk hospital.
