After getting jerked around for years by YesAsia and HKFlix, I finally happened onto Five Star Laser.
Five Star Laser is on the ground floor of a 3 story midi-mall, directly opposite an excellent Vietnamese noodle house.
They stock an excellent assortment of recent and not-so-recent Chinese movies on DVD, including the Celestial/Shaw catalog, the JoySales Platinum collection, and many, many more. The dvd's are all first-quality official releases, but many are priced BELOW what you would pay for bootlegs at other stores in the valley.
Many titles go into backorder, and it can take weeks for new stock to come from China, but that's the nature of this sort of business, so you can't complain. The owner is knowledgeable and helpful.
Overall, a great resource for some often very difficult to get films!
Pros: Only sells genuine releases, no bootleg
Cons: Many things go out of stock unexpectedly
