How to buy a gorillapod:
1) Get out of bed
2) Walk to MRT station
3) Take train to City Hall
4) Go to camera shop
5) Walk in, ask "do you have gorillapod in stock"?
6) Wait for them to bring it out
7) Flash your VISA card like a boss
8) Watch them tell you that you have to pay 1 or 2 or 3% more and keep it in your wallet like a boss
9) Take out cash
10) Gorillapod bought
Jokes aside, you can actually look at the Joby website, they even provide a guide to tell you what they think you should get? Information is widely available on the web for this sort of thing, perhaps you can consider looking for it beforehand before resorting to using Clubsnap as your automatic Googlebot. :bsmilie:
Cathay Photo carries Gorillapods, but there are also cheong versions everywhere.
Please note that you don't buy a tripod/gorillapod for a camera body, but rather for the total weight (body plus lens, etc) that you will need to support.
