Well, we used to have several good companies in the US that made tools. Now, the manufacturing picture is much changed. And, as Timothy points out, Singapore will have different tool availability than here. China produces a lot of stuff over a range of quality, so I think you'll be better off checking with folks there.

I think you could probably google bicycle tool sets in Singapore and you'll get a better idea of what's available.

I agree with Timothy on the point that a Torx T20 is the same on a bike and car. And even though there's probably a different mix of fasteners, ideally a tool set has combination wrenches, screwdrivers, pliers, needlenose pliers, a set of sockets (metric), an adjustable ("Crescent") wrench, a set of metric hex (Allen) keys and a set of Torx keys. Here, you have to add in imperial combo wrenches and sockets and hex keys. If you work on old Raleigh bicycles, add in Whitworth combo wrenches and sockets!

I differ on these points:
1) I don't think Park Tools are overly expensive (especially compared with Snap-On). I think that they're ok value for money, and I've gotten excellent customer service from Park. In any case, you could at least get an idea of what a bicycle tool set contains so that you can compare with locally available tools.
2) Craftsman tools used to be pretty good (I have a 40 year old, much used ratchet set), but current quality is pretty poor
