Should be Alan Photo. Alan Photo is one of the most reputable and cheapest camera shops here. They have another shop in Funan. Some of the salesman look like ah beng but they ok one. Used to buy from this golden hair ah beng in their Funan shop who always give me "brother price" and even stopped me a few times from buying cameras/lenses which he think are not good.
Alan Photo (Funan) tried to cheat my dad of $100.

The very fact that you have admitted that they had given you a 'brother price' means that their retail prices were elastic on a whim, and they wouldn't hesitate to also give 'carrot head' prices to certain target customers.
Stay away from all SLS shops level 1 to 3.
