I'm not up on the best places as the time and travel costs looking around HK stores is equal or greater than local shipping to my front door. However, to assist you here's a few tips: Check out HK based ecommerce stores like RobotKingdom and Robotoybase (formerly Chimungmung). They will provide updates on the day of release for brand new items. If they don't have them, they're not out. Look at Yahoo HK auctions. A lot of real stores sell their goods there for a 'buy now' price which is also a good indication of what is out and what is AND where to get them from.
