I don't think you should get it now from HK to get the best (not bestest) price, they have a tendency there to jack up the prices when supply is low and demand is high, unlike in SIN city......(may happen here too but not that frequent)
BTW: there is no 'bestest', best is already the best.....can not be better than best.
For leica electronic product,don't buy those without warrenty,now leica have a policy that all of its equipment price is about the same worldwide,so no difference to buy in Singapore or HK,some more Singapore agent will not service any thing that is not bought in Singapore coz item that sell in Singapore is abit more expensive than those sell in other country.
