Beware: Bes*cam (read this for your own good)

[Firefox]

I believe some cam brand do not indicate s/n on the card, just model no.

Yea.. The serial no. is filled in by hand..

I usually go to only AP @ SLS (but only deal with Anthony.. If he's not in, I won't be buying anything). For some items, I'd go to CP @ Peninsular.. Haven't really tried others but my friend's got good experiences with Parisilk @ Transit Road (outside Nee Soon Camp).. They offered to match the lowest price from any shop..
