Howdy! Youngstown, Ohio here. Have you tried your friendly neighbourhood Alembic dealers? There's bound to be a dealer listing somewhere on this website (mind you, I haven't been looking myself, but I also haven't bumped into one, either...). And, I can vouch for the dealer in Kent, Ohio, who has a lovely selection of Alembics in stock (including a RED, RED, RED vermillion-topped 4-string fretless set-neck).
My only words of caution for you: ONCE YOU HAVE PLAYED AN ALEMBIC, YOU CAN'T GO BACK TO ORDINARY INSTRUMENTS! There are Alembics, and the rest are planks. Hee hee!
Play nice,
David McK.
