Hi Chua,
Guess who am I? I am your lef-right man not long ago ... probably Sims had told you where he found me :) I have not started by dSLR journey yet .. have not decide on which camera to use. I think only PRO like you can identify a good buy. I am still looking for 5fps type exotic dSLR i will buy a second hand 20D canon when it someone offer ard 1k (fat hope ??? :D)
