Flyingbells, I think that you might be thinking of Galaxy, which is on the 8th floor of an industrial building. They carry a good selection at quite good prices. But you'll find no Saito's there either... Saito has been sold out in HK for as long as I remember. I only know of a few older models that were once for sale (50 and 70 Golden Knight).

Cuteflyer, where do you fly?
