SlowRain, I've had my Kyocera hand mill for only a few days and have been using it for french press coffee. It is very easy to break down and clean and it does produce a bit of fines when course grinding but not as much as my Mazzer does when grinding for french press. (I've been drinking french press for around 2 weeks since I gave up on the Gaggia).
I plan on also testing it on the new ECM when it arrives this week, I'll let you know what espresso is like.
The grinds are a bit static-y as the whole of the body is plastic with only the handle and spindle and spring being metal but it really only means the chaff sticks to the underside of the burr and stays out of the ground coffee until you've emptied it, then you can blow it off into the sink or whatever and a few taps gets the grinds out of the body once you've done.
They are $75 plus delivery from Orphan Espresso and as far as I'm aware (according to Kyocera in Europe) they are only available in Japan and not anywhere else so I can only assume O E are importing them to the states themselves or bought a few as stock if they or friends went to Japan.
You also asked in your PM where I got mine from, mine was a gift from a Japanese acquaintance
