华金,

Hong Kong doesn't have a taobao equivalent unless if you count eBay in but it's not as good, which is why everyone is using taobao these days, but probably not for buying mobile phones or video game consoles since prices in Hong Kong are way lower and taobao sellers are getting their products from Hong Kong. I would go to price.com.hk to check out the prices and get in contact with a store probably in Shun Shui Po and go pick it up. It can be tricky if you don't read Chinese, though.
