Hi Proud Dad:
Congrats on your impending arrival!
I think "Sling" has a good point. I just gave birth to baby #2 and have a 2 year old, and I am Baby Bjorning it until I am able to collect our new double stroller in the States.
There's no need to rush a double stroller purchase UNLESS you have the opportunity to visit a country where the prices and selection are superior to Singapore (i.e. U.S., Australia).
Having said that, there are a few things to take into consideration when buying a double stroller. First, what primary purpose will it serve? Long walks on pavement...or quick trips to the mall? If the former, then you might want to look into one of the all-terrain models (Phil & Ted's, Valco, Mountain Buggy, etc.) If the latter, perhaps a lighter model might be more appropriate (like the MacLaren). Whether you have a car or not is also a factor to consider, as some of the heavier models are a nightmare to fold up into the trunk of a cab.
I posted a related thread earlier this year, which you might find of some interest. In the end, we decided to go with the Phil & Ted's double (the new Sport model). We don't have a car, and I walk quite a bit -- those were the deciding factors in choosing this particular model.
