Where to buy Tamron AF 90mm f/2.8 Di SP macro lens in Singapore?

Anyone knows a good place in singapore where i can get a Tamron AF 90mm f/2.8 Di SP macro lens (nikon mount), preferably at a good price? Found some on Simlim for SGD400 with 3 years Tamron warranty but I'm reluctant to buy because they said there are alot of sellers up to no good. Any suggestions? Thanks in advance

Thanks for the response… Actually i've been reading reviews from photographers pro and the like. The downside i was able to read about was that its a dust vacuum apparently, but as a lens for a beginner like me, a photographer and trusted friend said its worth its pricetag.

Are you sure you want a Tamron lens? I ask this because I own one, the 18-200, and it's got
issues. Focus problems and aberrations. I don't recommend this brand.
