There's a chinese bookstore selling all chinese mags and books opp bras basah near the 7-11 side.
They are selling the chinese mags (1 mth ago usually) at about S$10. I fly frequently to China and if you want i may be able to bring back for you the current copies...
I saw some very current ones at Knowledge Bookshop the other day at Bras Basah Complex. Ironically Knowledge Bookshop is an indian-owned second hand bookshop... but they do have the latest chinese photography magazines.
Can try the shops at Bras Basar Complex. There is a shop on ground floor, selling many Chinese photography magazines from China, Hong Kong and Taiwan. Also other Chinese magazines like music, paint, gongfu, etc.
No title in particular but I managed to pick up a past issue of PhotoGal along an Orchard Road newspaper kiosk a few days back. My Chinese is not good so I just grabbed it for the pictures. It was cheap, only $4.50.
Thanks for all your help folks. I will go to Bras Basah to do some hunting.
