Is Mazzer Kony available in the U.S.?

I don't think anyone is carrying them in the US market but ESI, the US importer/manufacturer of La Marzocco, is now stocking a model called the Conico.

Looks to me like it might be the same machine. You might also do some snooping around for the Mazzer Robur. That appears at present to be the grinder of choice for serious espresso production where conical burrs are desired.
