When I bought the Koa, I had many long and wonderful conversations with the 2nd owner, Dalton. In those conversations I came to know him and was not only comfortable with him, but with the fact that he was well versed in his knowledge of the instrument, it's history, and his knowledge of Alembic in general. I bought it blind and never did anything but change strings on it. An instrument that is the quality of an Alembic is pretty much a no brainer once you establish your relationship with the seller. This is, of course, all my lowly opinion. A great advantage now is the presence of this forum. I bought the Koa before this forum was established, but recently we had an incident involving this forum and my old bass where a person in possession of the Koa out on the east coast was trying to sell it on the net and misrepresented the instrument in what I would call an illegal manner. The bass was recognized by people on this forum as my bass, I was notified, and the seller was contacted and made aware of the fact that he was being monitored by this forum. So, all that said, it is pretty easy buying an Alembic blind.
