The Canon EOS 500D has arrived in Hong Kong. Currently, only the kit version with EF-S 18-55mm f3.5-5.6 IS is avaialble. The body only version and kit with EF-S 18-200mm IS are not available yet.
I have checked the street price at Echo Photo & Audio, and they are selling the kit with 17-55mm for HK$6,000. If you want the body alone, they are willing to take the kit lens out and just sell you the body for HK$5,4oo.
You can read my Recommended Camera Shops in Hong Kong artilce on where to buy the EOS 500D in Hong Kong.
