Well, be careful about VPC and DMX. I bought a VPC-C6 from warehouse123.com and when it arrived, it turned out to be a DMX-C6. Not a big deal, but only because I never had problems with it (whew). DMX is the one from Asia that does not have warranty protection in North America. I seem to remember that somebody said that the new DMX models cannot be converted to English. (I was able to boot up the DMX-C6 and bungle my way through the menus and change it to English). So anyway, take care to get an English, VPC model.
I was half-prepared to make a credit card warranty claim if the camera ever failed, but because it says quite clearly on the box "no warranty in North America" I had a (sinking) feeling that the credit card company would notice that & decline any extended warranty. But as I say, I was fortunate and the issue never came up.
Grunchy, when did you order your C6? I ordered from warehouse123 serveral times, all of my purcahse are VPC model.
