Used X100 and SAB? Or X200?

So, basically I need a new camera, I sold all of my Canon gear. I'm in love with the X100, and want one. I'm also considering waiting until Photokina to see the x200.

If I do buy an X100, how widespread is the SAB thing? If I buy one brand new and it has it is that covered under warranty? Or if it's used? How does that work? I've seen a few x100s for $700-800 but I'm worried about the SAB.

Or should I just wait for the x200? My budget is under $2000. And I DON'T want interchangeable lenses anymore, so please don't suggest the x-e1/x-pro 1.
