    I've known about these for a few years at least, I almost bought one myself but backed off and I'm glad I did. I sure wouldn;t mind having one on hand though, just don't want to buy it.

    I can't find the link now but somewhere I have the link to the company that sells the machine itself shown in the links above.

    Is it just me or do the prices seem fairly reasonable? (For the wheels at least)

    The only problem is that the amakusa stones seem to have large inclusions of very widely differing grits which leave large scratches. I bought the red and white bench stones from epic edge. They're very slow (takes more than 40 strokes to produce burr vs 12 on a king 1k) and the finish they produce has scratches.

    There might be quality issues with some stones but mine are just fine no scratches no inclusions.
    As far as speed sometimes slow is good. Also consider this, once the wheel spins speed is not an issue, it will make equivalent of 40 passes in less than a minute.
