Hello
You can try M Technic Resources at 4th floor, escalator come out
turn left walk till end, corner shop ( if it is still there)
Don't worry, from my experience, these computer shops in sim lim
most probably wont want to rip ppl off for things like cable.
They would not want to rip you off for computer parts too, because
these are very competitive products and you can check the price
easily
Of course if they are charging you like $50 for a simple usb
cable you know it's not right already
However i remembered some years ago i went to buy a DKU-5 cable for
my then Nokia 6020, the guy in some handphone shop wanted to charge
me $85 ! Maybe it was original that's why it's so ex. But i did
find cheaper ones
