Leon, if you're serious about getting a Leica, try Don Chatterton. I got my first from him. There's also Ritz Collectibles in AZ, whose service is extremely personable. I got a black M6TTL body from them, which came in pristine shape and they even threw in the batteries for free.
So, there you go. If you CLICK HERE
you'll go to Don's website (it's not possible to order through his site, but e-mail or fax him about a camera and he'll be quick to reply. I've found calling him is even better). Now, HERE
is the website for Ritz collectibles. As I said above, their service is top notch, and they're nice on top of it!!
Good luck shopping!!
