Micro SX-8000 II or SZ-1

Mark, I understand the calculation but do not understand (from reading the webpage) where the 'gearing coefficient' comes from - higher speed flywheel providing gearing vs 33.3? rim-weighted platter increasing effective rotational inertia when compared to solid mass?

Let's not turn this into a discussion of Saskia, it's meant to be about the Micro Seikis. I used it as an example only.

Thuchan, there is a standalone Micro Seiki product called the HS-80, which was a high-speed inertia unit (made to be added to the 1500/5000/8000 series models). It would probably give much the same effect to the SX-8000 as the motor on the SZ-1 accomplishes. When they come up in the market, they are seriously expensive, but they are probably easier to find than an SZ-1.

You can see a picture here (about halfway down the page).

t bone,thanks a lot for your good advise. I put all my Katagana and Hirgana together (the Kanjis are all gone...), very interesting and I will definitely go for it.
thanks a lot

The last few I have seen go through the internet auctions in Japan have been in the area of JPY 150-175,000 (call it US$1500-1750). I would say they come up about 3-6 times a year.
