Agree... Buy and Sell on Clubsnap usually has pretty decent deals. But from experience, not everything can be found here. For 2nd hand shops, the one in Adelphi is called P&G. There's another one there but it seems like it's always closed. Haha! There's also The Camera Workshop at Peninsula Shopping Centre, same building as Ruby Photo. Then in that same building the other end got another P&G. The 2 P&G owners are brothers. Then next to Peninsula's P&G there's yet another store. Cross the road to Peninsula Plaza, there's one next to Cathay. Go upstairs 2nd floor got K-13 next to Bata I think... and the other end from K-13, there's another one but can't remember the name. Other than these, sometimes I go to Cash Convertors in the hope of finding good deals. But I guess photographers know better than to sell a good equipment to Cash Convertors... haha!
