I go to Hong Kong a lot, never bought any camera gear because when taken into account the risk, the savings and buying online from places such as Panamoz. It's hardly any different.
I wouldn't buy from one of those small Indy from Nathan Road for example, I picked the one in Harbour City because they are reputable and then I looked at a 5D4, it was the same as Panamoz prices so was not extortionate at all.
