Elwin, those pics I posted were actually to demonstrate that fps is not the most important factor. I had a 350D before but it's more difficult to take photos because the AF system is not good enough. Also, the time it takes for the camera to actually take the picture after you press the button, to me, is more of a factor. It's very important to have the right lens. All those recent HK Open pics were taken with a f2.8 lens (Red, myself, AChan etc.), Above all else, you need to learn the equipment to get the best out of it. Which means using it.
1) AF system - Canon's 20D, 30D, 400D all use the same AF system. 400D is very new - I don't if the shutterlag is longer than the 20D/30D, but it looks very promising as an entry level DSLR
2) F2.8 lenses - If you go for the brand name lenses i.e. Canon/Nikon brand, Canon is definately more expensive for the 70-200 range. The lens is all important and you should place as much emphasis on this as on the camera itself. Sigma is cheaper, Kwun and Jonassen have this lens.
3) I don't know about the Nikon D80,D200 but you should definately have a look at those.
Where to buy? Can check the prices between Msia and Sing. If I remember correctly, Msia is not that different to HK for other things like mobile phones but I haven't compared camera prices. Accessories are more expensive in Msia though.
