Are there any particular areas which have the best prices and biggest range of electronic goods?
A cheap and popular place to get electronics is Mustafa Shopping Center at Serangoon. But you said "best", is cheap best? There're other big electronic store like Harvey Norman, Best Denki, Courts etc. For computers stuff, go to Funan Digital Mall or Sim Lim square

Funan was great. Got great deals on external drives, camera lenses and netbooks there. But you have to shop around and haggle a bit. I heard from locals that tourists get ripped off at Sim Lim. Mustaffa has a bit of everything and specialize in nothing, so their electronic selection isn't stellar. about 10 years ago
