there are physical second hand shops around...penisular plaza..or the camera work shop located in the building in between penisular plaza and funan.
But i dun advise you to buy from there..the equipment probably not as good condition as those online from direct sellers, these stores usually display the cameras for sale on their shelf, think about it, the dust and stuff....even if they are in good condition..think about it..you will probably pay more as the store will need to earn some money too rite?
The best place is still B&S section. seriously.
*maybe u just wanna go take a look at the cameras is it..?*
