Arisx, welcome to ECF !
I know it is really tougher for you there to get e-cigs than just about anywhere else....
Your choice really depends on your needs. Read around a bit...read the stickies and reviews. After you get your post count above 5 you can start asking questions in other areas of the forum.
This is the link to the SG Vapers social group in here...
SG Vapers
They can help you with tips and tricks to get your e-cig and liquids.
Best of luck to you !
