In Sydney, almost everything there is more expensive than in Singapore maybe except for coffee and this HiRise dock. I bought the Twelve South HiRise for iPhone 5 & iPad Mini from Apple Store Sydney for AU$34.95 (S$41). In Apple Online Store (Singapore), the same dock is retailing for S$49.
This HiRise dock is compatible with all Apple Lighting devices maybe except for the iPad. Though I tested with an iPad Air and it fits fine, it is very flimsy and easily topple from the side of the dock.
