best place to get high quality japanese teaware online?

[trent]

I know of http://www.artisticnippon.com/, are there any others?

You can also find some japanese teaware at hibiki-an, o-cha and zencha.net

EDIT: some nice looking items http://www.rikyucha.com/index.php
(have anyone ordered from them?)

Holy Mountain Trading Company has some pretty neat stuff, although I've never ordered from them.

Tea Circle has some nice stuff if you're looking for Matcha gear.
