Matsuiyastore reliable, delivered within 4 days. with international warranty for new items. BH Photo too , if you buy items with international warranty they are good. I have bought from both and found them reliable without encountering any problems. I paid with PAYPAL.
nowadays since the US dollars dropping, u can find E-bay stuffs are relatively cheaper even with the shipping cost. Of course warranty issue and fraud is always there when it comes to E-bay stuffs, for me i bought my Olympus E-510 with one lens kit camera thru E-bay auctions first hand, which i think is the cheapest price i can get even compare with singapore price... ... S$770! Lastly my recommend E-bay powerful seller will be cametaauctions, auctions sometime is fun and addictive hahahahaha.
