William Thakker in Europe is an alternative source for the ART7. I'm guessing that he is an authorized AT dealer. You pay a bit more than with 2juki-- about 1K euro after deducting the VAT.
@chakster At the $1K price level I don't worry about a retip. By then there will likely be an ART10.
IIRC, the ART7 improves upon the Anniversary version with a stiffer and lighter liquid polymer coil former.
