I got back last monday. Our stay in Singapore was very pleasant. I was very surprised to find a small model shop right next to our hotel, albert court! We coming back from our little walk when I noticed familiar looking boxes. It was a model shop!  

 I was even more surprised to find some rare halcyon kits there. I had them all, though. They even had an original Space jockey kit!  

 (mine is just a recast) I probably would have got it, but the price was $230 (over 100€). Rare kits are expensive wherever you go. I then bought a set of tamiya british infantry and an academy us. mg set (you can't have too many of those).
Later that day we visited Hobby point at Tiong bahru plaza. That was an awesome store. If I had had more suitcases, I would have bought a stash of Tamiya kits, as they were cheap. Most tanks cost around 40$, in Finland the same kit can cost 40€ (almost double). There I only got two of Konami's collectable alien figures (I got aliens from the two first films. The original alien was fine as it came, but I think I'll repaint the "aliens" version). One interesting thing was that the great majority of sci-fi kits were gundam and other Japanese mechas. 
The last shop we had time to visit was a miniature hobby in the marina square. There I bought an afv club Wiesel. It was funny to notice that revell kits where as expensive as in Finland. Stuff imported from the other side of the globe is expensive.
Thanks again for the pointers. I had a great time in Singapore!
