Just one update. The Cullinan is actually the newest and most expensive. It is also seen as having the best quality facilities and construction (the developer does some of the best regarded high end properties in HK). I did check out the place just for kicks once, and the flats did have by far the best quality finishing, bathrooms, kitchens, etc, among all the Kowloon Station apartments. (It was a little hard to walk away after seeing those :-))
However, you do get much less square footage for your money there, so you may wish to heed the OP's advice. Unless budget is not a problem, or you'd rather have less living space in exchange for more luxurious facilities.
