canon name their csmeras different for the american, european and asian markets. Why? No idea, maybe to track where they are from. Same camera, different languages and a different name on the side.
If its cheaper and you want to risk it, go for it.
I'd thought as much. Canon don't offer their own warranty on it, but the company selling (called DigitalRev) offer their own equivalent warranty on it (which means you can get it sorted out locally).
I got the Kiss version £670 with 18-55mm 55-250mm lenses +8GB memory card including shipping. Canon say they will honour warranty. Sending company declared it as a gift with value £300, no duty charged!
