I just purchased a pair of Leica Duovids from Doug at cameraland. They are a Leica authorized dealer (I called Leica and confirmed this)and they are good to work with. I also saved about $300 bucks from what Cabelas sales them for and they shipped it for free. I would reccomend them to anyone.
I just bought some leica's from Doug--couldn't be happier! Doug goes the extra mile to make his customers happy. I wouldn't hesitate to buy from him again.
