Anybody from Singapore here??

I'm looking for a physical shop/s in SG that sell the Seido/Innocell Treo 680 Hi-Capacity 2400mAh Extended Battery. I've looked in the Worcell website and they have a partnership with MHT Electronics in SimLim Square, where they have this item in stock. However, friends are cautioning me from buying in SimLim coz of fake/low-quality stuff.

As I'd rather not use online buying for now, I wonder if somebody can recommend a shop they trust that sell this Seido battery.
