Got an email from them:
Thank you for your email. The cost of the annual Sebenzas depend on the size and the inlay. This year we are offering Satinwood, Bubinga or Ivory. If you let me know which size and inlay I would be happy to give you a price. Although all are larges are reserved, I many have some smalls available. We have not released any 2008 limited's yet. I imagine they will be available sometime next month or early December.
