Mark,
Indeed, there are few of them floating around right now. This doesn't mean you can't order one if you can afford it.
I have a Spyder, two Essences, a Europa, and I have a custom Series II being built. There is magic in all of them. What you might want to do is pick up a used Alembic, then save for the DW of your dreams, and order it. You won't be disappointed either way, trust me. I've used Alembics both at home and in a war zone, and believe me, not only do they sound and play beautifully, they're bullet proof.
Best of Luck,
Alan
P.S. The bass in the pictures at the above link is mine, as are the subsequent pictures of me with it at home.
