vfdfs2, your situation is different. Because you bought the G2 in Hong Kong and will be using it in the US, it is no need to buy the 100% retailed one. Even though you bought the original retailed one, the warranty will not be cover in the US. Saving more to get the one from "grey market" is a good choice. I also agree with you, however, that we still have to physically check out the camera (from grey market) carefully. If the store you bought the G2 from offer no exchange or repair service if there is something wrong with the grey-marketed G2, Canon will do nothing for you. So be warned!
